Answer 2

C. One-fourth mile over thirty-six seconds = 25 miles per hour.

Explanation:

We have been given that an elephant can run one over four of a mile in 36 seconds.

To find elephant's rate in miles per hour, we will convert our given time in hours as shown below:

`\frac{0.25\text{ mile}}{36\text{sec}}*\frac{60\text{ sec}}{1\text{min}}*\frac{60\text{ min}}{1\text{hr}}`

`\frac{900\text{ miles}}{36\text{hr}}`

`\frac{25\text{ miles}}{\text{hr}}`

Therefore, option C is the correct choice.
