Question

I need help on the second one

Answer 1

See explanation

Explanation:

First, let's convert feet to miles.

`\frac{63,756 \text{ feet}}{1}\cdot \frac{1 \text{ mile}}{5,280 \text{ feet}}=12.075\text{ miles}`

Next, let's convert minutes to hours.

`\frac{70 \text{ minutes}}{1}\cdot \frac{1\text{ hour}}{60\text{ minutes}}=(7)/(6)\text{ hours}`

Finally, let's find the unit rate.

`\frac{12.075\text{ miles}}{(7)/(6)\text{ hours}}=10.35\text{ mph}`

Hope this helps!

Answer 2

Sam's rate in miles per minute is 12.075 miles per minute.

The factor used to convert feet per minute to miles per minute is:

1 ft per minute= 1/5280 miles per minute

How to carry out Unit Conversion?

We are told that:

Distance ran by Sam = 63756 feet

Number of minutes he ran = 70 minutes

We are further told that:

5280 feet = 1 mile

Thus:

63756 feet = (63756 * 1)/5280

= 12.075 miles

Thus, the rate in miles per minute is 12.075 miles per minute
