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?

He only uses 4 at a time out of 5 tires.

 

This question seems hard, but it actually is this simple:

 

\(\frac{4}{5}*90000\)

 

\(\boxed{72000}\)
