Answer:

Below in bold.

Explanation:

He is running at 40/5 = 8 feet per second.

This is 8 * 3600 feet per hour as there are 3600 seconds in an hour.

In miles this is 8*3600 / 5280 miles ( there is 5280 feet in a mile.

So it is 28800/5289

= 5.45 miles per hour.

Answer:

12 x 40 = 480 feet per minute.

480 x 60 = 28800 feet per hour.

28800/5280 = 5.45 miles per hour.

Hope that helps.Thank you!!!
