An accurate clock shows 8:00 a.m. How many degrees does the hour hand rotate by the time the clock shows 2:00 p.m. the same day?

Problem restatementCompute the hour hand's rotation from 8 a.m. to 2 p.m.

Given data

• Hour hand rotates 360° in 12 hours → 30°/hour.
• Elapsed time = 6 hours (8 a.m. to 2 p.m.).

Step-by-Step calculationRotation = 30°/h × 6 h = 180°

Common pitfallsUsing the minute hand's 6°/min rate instead of the hour hand's 30°/h.
