Question

A car wash detailed 144 cars in 4 hours. At what rate did the car wash detail cars in cars per hour?

Answer 1

If this car wash took 4 hours to detail 144. 144/4 = 1/36 meaning that every hour they would detail 36 cars, we can double-check this and multiply 36 by 4 and we will get 144 meaning that this is true and that this car wash detailed 36 cars in an hour.
