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

Answer:
Every 12 hours hours hand runs 360 deg. So for every hour it makes 260/12=30 deg.

Since its 15 mins., which is 1/4 hour, the hour hand should move 30*1/4 deg=7.5 deg from 3.

So the Angle between minutes hand and hours hand is 7.5 Deg
