Question

Miguel runs 4 miles in 30 minutes. At the same rate, how many minutes would he take to run 10 miles?

Answer 1

He runs 1 mile in 7.5 minutes because 7.5x4 = 30. Then 7.5x10=75 so 75 minutes or an hour and 15 minutes

Answer 2

75

Explanation:

Use a proportion.

4 miles is to 30 minutes as 10 miles is x minutes.

4/30 = 10/x

2/15 = 10/x

2x = 15 * 10

2x = 150

x = 75

Answer: 75
