A clock shows 9:15. Through how many degrees will the hour hand turn by the time the clock shows 12:45?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 105°
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 9:15 to 12:45 \(=3\) hours 30 minutes \(=210\) minutes
Turn of the hour hand \(=210\times0.5^\circ=105^\circ\)
