Janet runs 2,640 feet in 5 min. How far will she have run in 15 minutes?

(15/5) * 2640 = ?

Thank u Ms. Sue

You're welcome, Amy.

To find out how far Janet will have run in 15 minutes, we can use the concept of proportions.

Let's set up a proportion between the distance Janet runs and the time she takes:
Distance / Time = Distance / Time

We are given that Janet runs 2,640 feet in 5 minutes. So, our proportion becomes:
2,640 feet / 5 min = Distance / 15 min

To solve for the unknown distance, we can cross-multiply:
(2,640 feet) * (15 min) = 5 min * Distance

Now, divide both sides of the equation by 5 min to isolate the Distance:
(2,640 feet) * (15 min) / (5 min) = Distance

Performing the calculations, we get:
7,920 feet = Distance

Therefore, Janet will have run 7,920 feet in 15 minutes.
