Answer:
80 minutes
Step-by-step 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.
