Teresa runs 7 miles in 80 minutes. At the same rate, how many miles would she run in 64 minutes?

Step-by-step explanation:

Let's set up a proportion using the following setup:

We know Teresa can run 7 miles in 80 minutes.

We don't know how many miles she can run in 64 minutes. Therefore, she can run x miles in 64 minutes.

We want to solve for x ( miles in 64 minutes). We must isolate x on one side of the proportion. x is being divided by 64 and the inverse of division is multiplication. Multiply both sides of the equation by 64.

x= 5.6 miles

Teresa can run 5.6 miles in 64 minutes.
