Between every two hours the hands of the clock coincide with each other for one time except between 11, 12 and 12, 1.In a day they coincide for 22 times. Example 1: Input: H = 9 , M = 60 Output: 90 Explanation: The minimum angle between hour and minute hand when the time is 9 is 90 degress. Convert time from 24 hour clock to 12 hour clock format. 1.for every 60 minutes of minutes hand,hour hand elapses 1 hour..so distance travelled by hour hand when the minute hand travels 1 min is 1/60 Therefore 1/4 times 1/12 = 1/48 of the clock. 29, May 17.

Writing code in comment? Find a time for which angle between hour and minute hands is given theta. When the hand's are in opposite directions, they are 30 minute spaces apart; Angle traced by hour hand in 12 hrs = 360°. Considering that hour hand is at 10, to make a 90-degree angle with the hour hand, the minute hand has to be at 1 or 7. For the first right angle, minute hand has to cover a relative distance of (1*30) = 30°. The minute hand rotates through 360° in 60 minutes or 6° per minute. Angle covered by hour hand qh= (H*60*0.5+M*0.5) = 0.5 (h*60+M) 0. Given two numbers, hour and minutes. When the minute hand is ahead of the hour hand, the angle between the two hands at M M minutes past H H 'o clock. So our formula is 30 ( H) So our formula is 30 ( 10) θh = 300. = 1 hour 5 5 / 11 minutes. How to find out angle between hour hand and minute hand of a clock | Abdullah Al Asif. Find if it's possible to rotate the page by an angle or not. Get an article everyday. We know in one circle total angle = 360 ° And if we divide a circle in 12 equal parts than each part have angle of = 360 ° 12 = 30 ° Now we can see that each part have angle of 30 °, And angle between hour hand and minute hand when time is 3 : 30 As : So Angle between 5 and 6 = 30 ° Angle between … this comes from the fact that a hour hand elapses 30 degrees for every hour(360/12) and minute hand elapses 6 degrees(360/60)..but for 6:50,the hour hand also elapses extra offset from its original position where it has to be there at 6:00 sharp..the offset is calculated as follows: 3.
