When the minute hand moves for 1 h 30 min, what is the angular distance covered by it?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 540°
The minute hand goes once round the dial, 360° in 60 minutes, so it turns through \(6^\circ\) every minute.
1 h 30 min \(=90\) minutes
Angle turned \(=90\times6^\circ=540^\circ\) (one full turn and a half)
