Question

Alicia ran 6 miles in 21 minutes. At this rate, how long will it take her to run 15

miles? Do not round

Answer 1

Answer: 52 minutes and 30 seconds

Explanation:

You are going to do cross multiplication for this. So 6 miles over 21 minutes is equal to 15 miles over x minutes. When we cross multiply this brings us to 315 over 6. Then we divide 315 by 6 getting us 52.5 minutes and .5 of a minute is 30

Answer 2

52.5 minutes

Explanation:

`21/6=3.5\\3.5*15=52.5`
