Question

Max ran 5 miles on Thursday. One mile is equal to 5,280 feet. Which proportion can be used to determine how many feet, x, Max ran on Thursday? HELP

Answer 1

1 mi/5280 ft = 5 mi/x ft

Explanation:

1 mi = 5280 ft

This is the first fraction:

1 mi/5280 ft

The second fraction:

5 mi/x ft

If the problem asked specifically for the value of variable x, you would multiply 5 miles by 5280 feet to find it.

The problem only asks for the set up of the proportion though so:

1 mi/5280 ft = 5 mi/x ft
