Jose ran 1/3 mile in 3 minutes and 15 seconds. Calculate Jose's rate in minutes per mile; in other words, the time that it would take for him to run 1 mile.

9.75 minutes

Step-by-step explanation:

First, we change into minutes: 3 minutes and 15 seconds = 3 + 15/60 = 3 + 1/4 = 13/4 minutes.

Then, 1/3 mile in 13/4 min, that means 1 mile (1 mile = 1/3 mile * 3) takes 13/4 * 3 = 39/4 minutes.

The answer is 39/4 = 9.75 minutes.
