Mariko is training for a race and now runs 6.5 miles in about 52 minutes. Write an equation to represent the number of minutes, n, she will take to run m miles at this rate.

52+n=m

6.5 / 52 m = n

Step-by-step explanation:

The rate is 6.5 miles / 52 minutes

We are going to run m miles in n minutes

m = 6.5 / 52 * n

We want to solve for n

Multiply each side by 52 / 6.5

6.5 / 52 m = 6.5 / 52 * n * 6.5 / 52

6.5 / 52 m = n
