Question

It takes Jill 2 hours to run 14.5 miles, At this rate, how far could she run in 3 hours? Btw, I am giving a lot of points if you get it correct!

Answer 1

21.75

Explanation:

To find how long she can run in a single mile, divide 14.5 by 2, giving you 7.25. If she runs three of those, (3 times 7.25), she runs 21.75 miles.

Answer 2

Answer: 21.75miles

Explanation:

Let the number of miles for 3 hours be represented as x

If 2 hours = 14.5 miles

Then, 3 hours = x

We Cross multiply

2x = 14.5 × 3

2x = 43.5

Divide both sides by 2

x = 43.5/2

x = 21.75

In 3 hours, Jill will be able to run 21.75miles. I hope this helps.
