Answer: Rachel can run 6.4 miles in 48 minutes.

Explanation:

Find the unit rate miles per minute then multiply by the minutes

4/30 = 1/7.5 One mile in 7.5 minutes. (Fraction equivalent 2/15)

2/15 × 48 = 6.4 miles

We can also use a ratio to solve:

4/30 = x/48 . cross multiply

4×48 = 30x

192 = 30x . Divide both sides by 30

192/30 = x

6.4 = x
