How much an angular distance will be covered by the minute hand of a correct clock in a period of 1 h 45 min?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 630°
The minute hand makes one full turn, 360°, every 60 minutes, so it moves \(360\div60=6^\circ\) every minute.
1 h 45 min \(=60+45=105\) minutes
Angle covered \(=105\times6^\circ=630^\circ\)
