Michelle can run 5.44 miles in 68 minutes. What is Michelle's average speed, in miles per minute ?
Phoenix [80]
5.44 miles ... 68 minutes
x miles = ? ... 1 minute

If you would like to know how many miles can Michelle run in 1 minute, you can calculate this using the following steps:

5.44 * 1 = 68 * x
5.44 = 68 * x      /68
x = 5.44 / 68
x = 2 / 25 = 0.08 mile

Result: Michelle can run 0.08 mile in 1 minute.
