Question

A walking track is 2 1/2 miles long. How many feet is that?

Answer 1

Answer:

13,200 feet

Step-by-step explanation:

In one mile, there are 5,280 feet.

You're trying to find how many feet are in 2.5 miles, so you can set up a proportion.

X = the number of feet in 2.5 miles.

$\frac{1 mile }{5280 feet} = \frac{2.5 miles}{X feet}$

To find X, all you need to do is cross multiply.

So,

X = 5280 × 2.5 = 13,200 feet
