Question

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

Answer 1

80 minutes

Explanation:

We can solve this problem using rule of three:

The ratio of number of minutes and number of miles is 24 to 3, that is, for each 24 minutes running, she runs 3 miles.

So, if to run 3 miles she needs 24 minutes, to run 10 miles, how much time she will need:

3 miles -> 24 minutes

10 miles -> X minutes

3/10 = 24/X

X = 10 * 24 / 3 = 80 minutes.

She will take 80 minutes to run 10 miles.
