Question

Josie is training for a race.The ratio of the number of minutes she run to the number of miles she run is 24 to 3 . She plan to run 10 miles. How many minutes will it take her

Answer 1

Explanation:

Set this up as a ratio of minutes to miles. If it takes her 24 minutes to run 3 miles, the ratio that expresses that is

`(24)/(3)`

If you want to find out how long in minutes it will take her to run 10 miles, the number of minutes is our unknown with 10 in as miles and the ratio completed looks like this:

`(24)/(3)=(x)/(10)`

Cross multiply to get 3x = 240 so

x = 80 minutes
