The length of the wheel rim is 48 cm. At some distance, the wheel made 60 revolutions. How many revolutions

The length of the wheel rim is 48 cm. At some distance, the wheel made 60 revolutions. How many revolutions will a wheel with a rim length of 36 cm make at the same distance?

First you need to find the distance that the wheel has traveled. For this:
1) 48 * 60 = 2880 (cm) passed the wheel
Now you need to find out how many revolutions the wheel will make at the same distance. For this:
2) 2880: 36 = 80 (o.) Passed the second wheel
Answer: 80 revolutions made a wheel at the same distance with a rim length of 36 cm.
