Answer 1

Answer: C.
`\frac{264\text{ feet}}{\text{ minute}}`

Explanation:

We know that 1 mile = 5280 feet

and 1 hour = 60 minutes.

Given : A track runner was timed at 3 miles per hour.

By using UNITARY METHOD, To convert miles per hour into feet per minute , we multiply it by 5280 and divide it by 60 , we get

`3\text{ miles per hour}=\frac{3\text{ miles}}{1\text{ hour}}\\\\=\frac{3*5280\text{ feet}}{60\text{ minute}}\\\\=\frac{264\text{ feet}}{\text{ minute}}`

Hence, they run
`\frac{264\text{ feet}}{\text{ minute}}`.

Answer 2

C. 264 feet

Explanation:

Firstly, one mile is equivalent to 5280 feet.

The runner ran 3 miles, so you times that by 3.

After that, you take that number, and divide it by how many minutes are in a hour, and then you should get what i gave to you.

5 stars would be nice. :D
