Question

Aidan walked 440 feet in one minute. Find his average rate in miles per hour.

Answer 1

Take into account the following equivalences as conversion factors:

1 mi = 5280 ft

1 h = 60 min

Then, you have:

$440\frac{ft}{\min}\cdot\frac{1mi}{5280ft}\cdot\frac{60\min }{1h}=5mph$

Hence, the average rate is 5 miles per hour
