When the minute hand covers a distance of 1 hr 15 min, then what is the angular distance covered by it?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 450°
The minute hand goes once round the dial, 360° in 60 minutes, so it turns 6° every minute.
1 hr 15 min = 75 minutes
Angle turned: \(75\times6=450\)° (one full turn of 360° and a further 90°)
