Question

Kaitlin runs 5 miles in 38 minutes. At the same rate, how many miles would she run in 57 minutes?

Answer 1

7.5 miles

Explanation:

Since she runs 5 miles in 38 minutes, she runs
`(5)/(38)` miles in one minute.

Hence, in 57 minutes she runs:

$ \frac{5}{38}\times 57$ miles = 7.5 miles

Answer 2

7.5 miles.

Explanation:

5/38 = x/57

Multiply each side by 57.

285/38 = 7.5.
