Jill can run 20 miles in three hours at a steady
rate. How many minutes
will it take her to run
five miles?

45 minutes

Step-by-step explanation:

Change 3 hours to minutes

1 hours = 60 minutes

3 hours = 180 minutes

Using proportions

20 miles          5 miles

Using cross products

20x = 5* 180

20x =900

Divide each side by 20

20x/20x = 900/20

x =45
