CLOCKS:
- The clock is a circle and there are 12 hour divisions in it. Total Angle=360°. Angle between 2 hours = 30°.
The hour hand completes 30° in an hour i.e. 60 min. So, speed of hour hand=0.5°/min.
The minute hand completes 360° in an hour i.e. 60 min. So, speed of minute hand=6°/min.
In a well functioning clock, both hands meet after every 720 / 11 Mins. - It is because the relative speed of the minute hand with respect to the hour hand = 11/2 degrees per minute.
- Angle between hands at H hours M minutes = |30H - 11M/2| degrees
