Question

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

Answer 1

38 mins = 5 miles

1 min =  5/38 miles

57 mins = 5/38 x 57 = 7.5 miles


Answer: 7.5 miles

Answer 2

You can use a proportion.

5 is to 38 as x is to 57.

$\dfrac{5}{38} = \dfrac{x}{57}$

$x = 57 \times \dfrac{5}{38}$

$x = 7.5$

Answer: 7.5 miles
