Question

Mark walked 21,129 feet in one hour. At that speed, about how many miles will he walk in two hours

Answer 1

Explanation:

First you need to make sure that the numbers you are working with are the same type of unit. 1 mile is equal to 5,280 feet.

Next you have to do 21,129 divided by 5,280 which is 4.00189394.

Third, you can round that to 4

Finally, 4 miles/hour × 2 hours = 8 miles (rounded to four decimal places).

Hope this helped!
