How long does it take for a minute hand to cover the whole circumference of the circular clock once?
- 24 hours
- 1 hour
- 20 minutes
- 60 seconds
Hint:
It takes 1 hour for a minute hand to cover the whole circumference of the circular clock once
The correct answer is: 1 hour
- Every hour, or 60 minutes on both planets, the minute hand completes a full circuit.
- There are 24 hours in a day on Earth, and the hour hand of an Earth clock completes a full circuit every 12 hours.
