The hour hand of an ordinary clock moves how many degrees in a consecutive span of 180 minutes?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 90 degrees
The hour hand goes once round the dial, 360° in 12 hours, so it turns \(\frac{360}{12}=30^{\circ}\) an hour, or \(\frac{1}{2}^{\circ}\) a minute.
180 minutes \(=\) 3 hours
Turn of the hour hand \(=3\times30^{\circ}=90^{\circ}\), for example from 12 to 3
