Answer 1

To find out how long 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 taken for one mile: $$\text{Time per mile}=\frac{\text{Total time}}{\text{Total distance}}=\frac{36\text{ minutes}}{4\text{ miles}}=9\text{ minutes/mile}$$

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