How much angular distance will be covered by the hour hand of a correct clock in a period of 2 hours and 16 minutes?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 68°
The hour hand goes once round the dial, 360° in 12 hours, at a steady rate.
In 1 hour it turns \(360\div12=30^\circ\), so in 1 minute it turns \(30\div60=0.5^\circ\)
2 hours 16 minutes \(=120+16=136\) minutes
Angle turned \(=136\times0.5=68^\circ\)
