How many times does a tire with a diameter of 22 in. rotate when it travels a mile?
**Tip: As there are 63,360 inches in each mile, 63,360 divided by circumference = number of full rotations. Round up to the next whole number.
*
458 rotations
1831 rotations
167 rotations
917 rotations
1831 rotations
The formula to calculate the number of rotations a tire makes in a mile is:
Number of rotations = (Distance traveled in inches) / Circumference of the tire
Given that the circumference of a tire with a diameter of 22 in. is about 69.08 in. (using the formula for the circumference of a circle: C = π * d), we can calculate the number of rotations:
Number of rotations = 63360 in / 69.08 in = 917.29
Since we need to round up to the next whole number, the tire will make 918 rotations in a mile.
