Clock Angle Calculator. Calculate determines the angle between the hands on a clock using clock angle calculator. Just select the time in an hour and minutes. Every 60-second, minute hand moves his position, then there is an angle between both hands hour and minute. *If you liked it then please provide feedback with your experience However, the hour hand will actually be between the 8 and the 9, since we are looking at 8:15 rather than an absolute hour mark. 15 minutes is equal to one-fourth of an hour. Use the same equation to find the additional position of the hour hand. We are looking for the angle between the two hands of the clock The hour hand moves 360 degree in 12 hour. The hour hand moves 30 degree in 1 hour. The hour hand moves 0.5 degree per minute. So hour hand must be between 3 and 4: Hence angle covered by hour hand is 30 × 3 + 0.5 × 10 = 95 degree. The minute hand moves 360 degree in 1 hour. The minute hand moves 360 degree in 60 minutes Again the minute hand has to sweep through (30 x 5) ie 150° for reaching the figure 5 to show 25 mins. Simultaneously the Hour hand will also rotate for 25 mins. Thus starting from the mark, 3 the hour hand will cover an angle = (25 x 30) / 60 = 12.5° Hence, Angle between Hour and the Minute hand = (60 - 12.5) = 47.5 Calculate the Angle between 12 and the Hour hand 10: Since there are 360 degrees in a full circle (clock), and there are 12 hours, each hour represents 360/12 = 30 degrees. So our formula is 30 ( H) So our formula is 30 ( 10) θh = 300. Next, we know how each minute is 1/60 of an hour. Each hour represents 30 degrees

The hour hand of a 12-hour analog clock turns 360°in 12 hours, and the minute hand rotates through 360°in 60 minutes. So, we can calculate the angle in degrees of the hour hand minute hand separately and return their difference using the following formula: Degree(hr)= H×(360/12) + (M×360)/(12×60) Degree(min)= M×(360/60 * The simplest way to think of this is that each hour is made up of 30° and that the hour hand will have moved one quarter of an hour past three o'clock*. ¼ x 30° = 7.5° If you are interested in exactly what time the two hands overlap, when there zero degrees between them; I deal with this in Puzzle #35 So, formula is: 1 minute = 6 degree. Since clock time is quarter past 5 i.e. 5:15, let's calculate the distance covered by hour hand when minute hand covers 15 minute. Using unity Rule: When Minute hand covers 60 minutes, Hour hand covers 5 minute distance. When Minute hand covers 1 minutes, Hour hand covers 5/60 minute What will be the angle between hour hand and minute hand if clock shows 8/30 pm? The hour hand on a clock moves 360/12 = 30 degrees per hour.So at half past any hour, including at 8:30, the hour hand has moved 1/2*30 = 15 degrees from the position at that hour, or at 8 o'clock. The minute hand is at the digit six. If the hour hand were at the.

Here, the time is 7:20 or or Angle traced by hour hand in 12 hours = Angle traced by hour hand in 1 hour = Angle traced by hour hand in = Angle traced by minute hand in 60 minutes = Angle traced by minute hand in 1 minute = = Angle traced by minute hand in 20 minutes = ∴ The required angle between the hour hand and minute hand ** Correct answer: The angle measure between any two consecutive numbers on a clock is **. Call the 12 point on the clock the zero-degree point. At 4:45, the minute hand is at the 9 - that is, at the mark. The hour hand is three-fourths of the way from the 4 to the 5; that is, , the desired measure And angle between hour hand and minute hand when time is 3 : 30 As : So Angle between 5 and 6 = 30 ° Angle between 5 and 4 = 30 ° Remaining angle ( between 4 and hour hand ) = 1 2 ( 30 °) = 15 ° SO, Angles between hands of the clock at 3 : 30 = 30 ° + 30 ° + 15 ° = 75 ° ( Ans

The angular speed of hour hand is 30 degree per hour = 0.5 degree per minute. The angular speed of minute hand is 360 degree per hour = 6 degree per minute. Stop the hour hand by applying a negative speed of 0.5 degree per minute. The hour hand remains at rest at 10 This is the Solution of Question From RD SHARMA book of CLASS 11 CHAPTER MEASUREMENT OF ANGLES This Question is also available in R S AGGARWAL book of CLASS. The hour hand covers 30 degrees in 60 minutes of the minute hand. Thus in 15 minutes it covers 30*15/60 = 7.5 degrees. So the hour hand is at 90+7.5 = 97.5 degrees from 12. So the angle between the hour and minute hands of a clock when the time is a quarter past three is 97.5-90 = 7.5 degrees 1 minute = 6 0. Here minute = 45. Angle covered by minute hand = 45 × 6 = 270 0. Angle covered by hour hand = 6 × 30 + 45 × ½ = 180 + 22.5 = 202.5 0. Angle between hour and minute hands = 270 - 202.5 = 67.5 0. Hence, angle between hour and minute hands is 67.5 0. Formula to calculate angle (N) between Minute hand and hour hand is D) 11 10/11 minutes past 2. Answer & Explanation Answer: A) 1 10/11 minutes past 2. Explanation: Since, in one hour, two hands of a clock coincide only once, so, there will be value. Required time T = 2 11 H × 30 + A o minutes past H. Here H - initial position of hour hand = 2 (since 2 O'clock) A° = Required angle = 0° (Since it coincides) T.

* Hour angle (from 12 o'clock): 360 * (hour % 12) / 12 + 360 * (minutes / 60) * (1 / 12) Angle between hour and minute: (hour angle - minute angle) % 360 By simple arithmetic, this reduces to 30 * hours - 5*.5 * minutes. Share. answered Oct 2 '15 at 2:38. Dhiraj Himani The angle between the 5 and the 6 is 30°. The angle between the 4 and the 5 is 30°. The angle between the 3 and the 4 is 30°. The remaining angle is ½ × 30° = 15°. So the angle between the hands of a clock at 2:30 = 30° + 30° + 30° + 15° = 105° Time statements such as 'a quarter past', 'half past' and 'a quarter to' obviously are linked to fraction. In the fraction mode a circle sector is painted from 12 o'clock to the minute hand position. Two large fractions are displayed the fraction of an hour shows the unsimplified fraction of minutesÃ·60 The full angle made by the hour hand will be 150°+15° = 165°. The minute hand at 5 o'clock is at 12, and hence the angle made is zero. In 30 minutes, it will travel a distance of 30 minutes with a speed of 6° per minute. Therefore, the total distance travelled will be 30 minutes*6° = 180 ° The angle between the hour hand and the minute hand of a clock at half past three is - 513485

At 6 o'clock , the angle between the hour and the minute hand will be 180° IN 13 minutes, the angle made by the hour hand = 13/2° IN 13 minutes, the angle made by the hour hand = 6°× 13 = 78° The angle between the hour and minute hand = 180° - 78° + 13/2° = 95.5° = 95.5° × π/180° = 1.67 radian (4) 5 minutes past The easiest way is to multiply 1/12 (for the hour) times 360 degrees (we arrive at 30 degrees as anticipated) then, for the quarter hour passed to get to 15 past, mulitply 1/4 by 30 degrees and you get 7.5 I got this question and believe me it was hard to think cool under that kind of pressure but just remember to think aloud In a minute, the hour hand moves by half degrees and the minute hand moves by six degrees. The angle at 3 o'clock between the two hands is 90 degrees. For them to coincide, it should move m minutes. 90 = 0+(6m− 2m. . ) 180= 12mm. 180= 11m. m = 16114 By the time the minute hand has gone all the way round the clock and is back at 12, one hour later (i.e., at 1 o'clock), the hour hand has moved to 1. Five minutes later, the minute hand reaches 1, but they don't quite meet there because the hour hand would have moved 1/12 of the distance between 1 and 2, to indicate 5 minutes past 1

1. Move the minute hand 15 minutes at a time until the grandfather clock chimes the hour. Then stop. Do not be concerned where the minute hand is pointing at this time. 2. Leaving the minute hand in this position, unscrew the nut that holds the hands in place. 3. Remove the minute hand. 4. Re-position the minute hand so that it is pointing to. The Hour Hand makes a full rotation in 12 hours and will therefore move at 30° per hour. At our first overlap just after five past one the Minute Hand will have done one full rotation plus the bit we are interested in. The Hour Hand will have done just a part rotation of 't' times it's speed. Hour Hand = Minute Hand 30t = 360t - 360 t = 12 (t. The small hand on a clock that shows the hours. It goes once around the clock every 12 hours (half a day). Example: in the clock on the left, the hour hand is just past the 8 so you know the time is just past 8 o'clock. (The large hand is the minute hand and it shows that it is 22 past the hour, so it is 22 past 8). See: Minute Hand It means there is a quarter of an hour (15 minutes) left until 12:00. A quarter to 12 is before 12:00. Secret trick: at quarter to, the minute hand always points to the 9! O'clock. Twelve o'clock is the same as 12:00. The minute hand is at the top of the clock on the 12. One o'clock, two o'clock and three o'clock are all words you can.

On a standard analog 12 hour clock, it takes 720 minutes for the hour hand to go around the clock once (360 degrees), so every minute the hour hand advances by 1/2 of a degree, not 1/60th of a degree * At what angle the hands of a clock are inclined at 15 minutes past 5?

What are the (a) magnitude and (b) angle from a quarter after the hour to half past, the (c) magnitude and (d) angle for the next half hour + The hour points slightly past 4. Since a third of the hour has passed (20' = 60' / 3), then the minute hour has moved a third of the way between hours. Hence the hand is at 120º + 30º / 3 = 130º. The difference between the two hands is 130º - 120º = 10º So I guess you get some poits for saying 0º, more points for saying 10º The minute hand will be 4/12 = 1/3 of 360 degrees clockwise from up, so 120 degrees. The hour hand will be 10/36 = 100 degrees clockwise from up. 120 - 100 = 20 degrees

A circle has a 360° angle. So, the hands of a clock also travel as complete 360° to complete 1 hour. So, the angle in between each hour can be calculated as - 360/12 = 30° So, at 7.20, the hour's hand will be in between 7 and 8 and the minute's hand will be near 4. Since 1 hour is 60 minutes, 20 minutes means it is 1/3rd of an hour. So, it. View Answer. View Answer. A watch which gains 5 seconds in 3 minutes was set right at 7 a.m. In the afternoon of the same day, when the watch indicated quarter past 4 o'clock, the true time is: A. 59 7 12. min. past 3. B. 4 p.m. C If you look at a clock and the time is 12:15, what is the angle between the hour and the minute hand? We know that at 12:15 the angle is slightly less than ¼. Why? Because the hour hand needs to move from 12 to 1 over the course of an hour, the hour hand is a little past 12 (and thus the angle is a bit less than 90)

Solution: A correct clock would have completed 12 hours by 8 pm. But the faster clock actually covers 5 min. extra in one hour. So, it will cover 12 x 5 = 60 minutes extra. Therefore, when the correct clock would show 8 pm, the faster clock will show 60 minutes extra i.e. 9 pm. Example 2: A watch loses 5 seconds in one hour and was set right at. Clocks can also use hands to show us the Hours and Minutes. We call them analog clocks. The Little Hand shows the Hours: 2 Hours : 5 Hours: The Big Hand shows the Minutes: 30 Minutes or Half-Past : 15 Minutes or Quarter-Past: Using both the Big Hand and Little Hand lets us know exactly what time it is: 2:30 or Half-Past Two : 5:15 or Quarter.

3. Use the big hand to read the minutes. Take the number that it is pointing to, and multiply it by 5 to get the minutes. When it is pointing to the 12, it is the top of the hour. If the big hand is an a mark between the numbers, count the marks, then add them to the minutes (clock number times 5). For example How many degrees are there in the angle between the hour and minute hands of a clock when the time is a quarter past three? Given an array whose elements are sorted, return the index of a the first occurrence of a specific integer. Do this in sub-linear time.

Setting the Hands: When setting the clock to time, move the minute hand, pausing at each hour (and half-hour for some clocks) for the clock to strike. Never move the hands counterclockwise past 6 or 12. Winding - Eight Day clock: Wind the clock once per week, preferably on the same day each week

• The minute hand goes around once for every hour. When the minute hand is on the 12, the hour hand is pointing exactly at an hour. When it has gone exactly between the hours, it is called half-past the hour. When the minute hand points to the 3, it has gone a quarter of the way around, so it's a quarter past the hour. 8 let's look at this clock and see if we can tell what time is shown on it first thing when we look at a clock we have two hands and that's because time is told in two parts time is told in hours that's part and on a clock the hours are represented by the shorthand and then the other part is minutes and on an analogue clock like this one minutes are represented by the longhand so let's look. If you have to hold or adjust your scope turrets 1.5 mils for a 10-mph wind, just use .75 mils if it's only blowing at 5 mph. If it's blowing 20, and you are skilled enough to take a shot in. In every hour, as the hour hand moves across 5 minute spaces, the minute hand moves across 60. That means the minute hand gains 55 min sp. over hour hand in 60 min. Thus, between the nth and (n+1)st hr, to overlap the minute hand must gain the 5n min sp. that exists between them when the clock strikes n hrs

So, to turn the clock back one hour the sync pulse would need to be sent 20 times seperated by 3 minutes thus holding the hour and minute hands fixed. To advance the clock one hour the sync pulse would need to be sent for 23 hours once each 3 minutes stoping the clock for just short of a day The article seems like it was written somewhat quickly. I think the best part of the movement is that the minute hand is geared to the seconds hand so that, for example, at 30 seconds into the minute the minute hand will be half way between minute markers. When the seconds hand passes 12, the minute hand is precisely over the minute marker

An hour (symbol: h; also abbreviated hr) is a unit of time conventionally reckoned as 1 ⁄ 24 of a day and scientifically reckoned as 3,599-3,601 seconds, depending on conditions.There are 60 minutes in an hour, and 24 hours in a day. The hour was initially established in the ancient Near East as a variable measure of 1 ⁄ 12 of the night or daytime.Such seasonal, temporal, or unequal. Your children will understand how to read a clock in no time with these worksheets.They have different examples of clock faces with the hands at different positions. Help your children understand o'clock, half past, quarter past and a quarter to, on an analogue clock face. There is a space under each clock to write the answer.Could be used at the start of your Maths teaching unit on time. In my clock I changed the following compared to the words on Wouter's clock. MINUTES changed to MINUTE at 1 minute past and 1 minute to the hour. Added an A before the QUARTER past and QUARTER to the hour. At Midday changed the time to read TWELVE OCLOCK IN THE AFTERNOON. At Midnight changed the time to read TWELVE OCLOCK AT NIGHT
