An accurate clock shows the time as 3:00. After that, the hand hour has moved 135°, the time would be:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 7:30
The hour hand sweeps 360° in 12 hours, that is 30° every hour or 0.5° a minute. Turning through 135° therefore takes 135 ÷ 30 = 4.5 hours, that is 4 hours and 30 minutes.
Starting from 3:00, the time after that interval is 7:30.
