When the minute hand covers a distance of 1 hr 10 min, then what is the angular distance covered by it?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 420°
The minute hand goes once round the dial, 360° in 60 minutes, so it turns 6° every minute.
1 hr 10 min \(=70\) minutes
Angle turned \(=70\times6^\circ=420^\circ\)
