Question

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.

Answer 1

52+n=m

Explanation:

Answer 2

6.5 /52 m = n

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
