Puzzle_11

Note :- Winner of Puzzle_11 will be announced in the next Puzzle ( Puzzle_12 )

--------------------------------------------------------------------------------------------- Puzzle: What is the angle between the minute hand and the hour hand at 3:15 on an analog clock?
---------------------------------------------------------------------------------------------

Solution: 12 hours on the clock make 360 deg.
so 1 hour is 30 deg.
The hour hand will be directly on the 3 when the minute hand is at 12 (3:00).
After 15 minutes or 1/4 of an hour,
the hour hand will be 1/4 * 30 deg = 7.5 deg. away from the minute hand

Cheers..
