Oscar is training to compete in a cross country meet at his school in a week. He runs a total of 7 miles and 84 minutes. What is the unit rate of minutes per mile?

Answer 1

To find the unit rate of minutes per mile, we need to divide the total number of minutes by the total number of miles.

$\frac{84\text{ minutes}}{7\text{ miles}} = 12\text{ minutes per mile}$

Therefore, the unit rate of minutes per mile is $\boxed{12}$.
