At exactly 3:15, what is the angle between the hour hand and the minute hand?
Explanation: At 15 minutes, the minute hand is exactly at the 3 mark (90°). However, the hour hand has moved slightly toward the 4. In one hour (60 mins), the hour hand moves 30°. In 15 minutes, it moves 15/60 * 30° = 7.5°.
