Kyle has five tires but only uses four at a time on his car. He has rotated the five tires on his car so that each tire has been on the car for the same number of miles.If the car has been driven 90,000 miles, for how many miles was each of the five tires on the car?

4/5 = 0.8

0.8 * 90,000 = 72,000

4/5=0.8

0.8*90000=72000

To find out how many miles each tire was on the car, we need to divide the total number of miles driven by the number of tires.

In this case, Kyle has five tires but uses only four at a time, meaning one tire is always in reserve. Since the tires are rotated, each tire should have been on the car for the same number of miles.

First, let's find the number of miles driven by each tire set. Since there are four tires on the car at any given time, we divide the total number of miles driven by four:

90,000 miles / 4 tires = 22,500 miles per tire set

However, remember that Kyle has five tires in total, which means each of the four tire sets is made up of a different combination of tires. Since each tire set has the same total mileage, we need to find the average mileage for each tire.

To do this, we divide the total mileage per tire set by the number of tires in each set:

22,500 miles / 4 tires = 5,625 miles per tire

Therefore, each of the five tires was on the car for approximately 5,625 miles.
