Answer:

See explanation

Step-by-step explanation:

First, let's convert feet to miles.

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

Next, let's convert minutes to hours.

$\dfrac{70 \text{ minutes}}{1}\cdot \dfrac{1\text{ hour}}{60\text{ minutes}}=\dfrac{7}{6}\text{ hours}$

Finally, let's find the unit rate.

$\dfrac{12.075\text{ miles}}{\frac{7}{6}\text{ hours}}=10.35\text{ mph}$

Hope this helps!
