A clock shows 2:15. Through how many degrees will the hour hand turn by the time the clock shows 3:45?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 45°
The hour hand goes once round (360°) in 12 hours, so it turns 30° in an hour, that is 0.5° in a minute.
Time from 2:15 to 3:45 \(=1\) hour 30 minutes \(=90\) minutes
Turn of the hour hand \(=90\times0.5^\circ=45^\circ\)
