The circumference of one wheel is 1.5 m. After covering some distance, it made 96 revolutions.

The circumference of one wheel is 1.5 m. After covering some distance, it made 96 revolutions. What is the circumference of the other wheel if, when traveling the same distance, it makes 62.5% of the revolutions of the first wheel?

First, you can find the distance that the wheel has traveled. To do this, multiply the circumference by the number of revolutions. Using the data, you need to multiply 1.5 meters by 96 revolutions.
1.5 * 96 = 144 m
Now let’s find the number of revolutions of the second wheel. To do this, we will compose a proportion and use its main property: the product of the extreme terms is equal to the product of the middle terms.
96 turns – 100%
x revolutions – 62.5%
96 / x = 100 / 62.5
x = 96 * 62.5: 100 = 60 revolutions
To find the circumference of the second wheel, you need to divide the distance by the number of revolutions, that is, divide 144 meters by 60 revolutions.
144: 60 = 2.4 m
The circumference of the second wheel is 2.4 meters.
