An accurate clock shows 10 o’clock in the morning. Through how many degrees will the hour hand turn by the time the clock shows 2 o’clock in the afternoon?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 120°
The hour hand goes once round (360°) in 12 hours, so it turns 30° in each hour.
From 10 a.m. to 2 p.m.: 10 to 12 is 2 hours and 12 to 2 is 2 hours, 4 hours in all
Turn of the hour hand \(=4\times30^\circ=120^\circ\)
