Answer 1

To find the time it took Carla to run one mile, you can divide the total time by the total distance.

Carla took 36 minutes to run 4 miles.

To find the time per mile:
\[
\text{Time per mile} = \frac{36 \text{ minutes}}{4 \text{ miles}} = 9 \text{ minutes/mile}
\]

So, the correct response is:
**9 minutes/mile**.
