What is the angle between the hour and minute hands at 3:00?

Explanation: Each hour mark on a clock represents 30° (360° ÷ 12 hours). At 3:00 the hour hand is at the 3 (90° from 12) and the minute hand is at 12 (0°), so the angle between them is 90°. Remember this rule — each hour gap is always 30°.
