The angular distance covered by the minute hand in 1 hour 20 minutes is:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 480°
The minute hand goes once round the dial, \(360^\circ\), in 60 minutes, so it turns \(6^\circ\) every minute.
1 hour 20 minutes \(=80\) minutes
Angle turned \(=80\times6^\circ=480^\circ\), that is, one full turn and \(120^\circ\) more
