A wheel rotates 12 times in a minute and moves 5 metres during each rotation.
What is the time taken for the wheel to move through 930 metres?
Sol:
For one rotation, distance moved = 5 metres
For 12 rotations, distance moved = 12 × 5 = 60 metres
Distance covered in 1 minute = 60 metres
Total distance covered by the wheel = 930 minutes
Total time taken = 930/60=15.5 minutes.
