Question

Leila runs 4 miles in 30 minutes. at the same rate, how many miles would she run in 48 minutes?

Answer 1

6.4

Explanation:

Use a proportion.

4/30 = x/48

Reduce.

2/15 = x/48

Cross multiply.

15x = 2 * 48

15x = 96

x = 6.4

Answer: 6.4 miles

Answer 2

6.4 miles

Explanation:

We can use a ratio to solve

4 miles x miles

------------- = ----------------

30 minutes 48 minutes

Using cross products

4 * 48 = 30x

192 = 30x

Divide each side by 30

192/30 = x

6.4 miles =x
