Ravi set his new wall clock going at 12 noon. Through how many degrees has its hour hand moved when the clock shows 1:48 p.m.?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 54°
The hour hand goes once round (360°) in 12 hours, so it turns 30° an hour, that is 0.5° a minute.
Time from 12 noon to 1:48 p.m. \(=1\) hour 48 minutes \(=60+48=108\) minutes
Turn of the hour hand \(=108\times0.5^\circ=54^\circ\)
