How long do you need to walk?

Question

The gym is 80 feet long and 40 feet wide. How many times do need to walk around the gym to walk one mile (5,280 feet)?

Answer 1

First, we need to find the perimeter of the gym. The equation to find the perimeter of a rectangle is P = 2(l+w). The problem tells us the length (80 ft.) and the width (40 ft.). So, P = 2(80+40). P = 240. Another way to find the perimeter is by drawing a picture.

 

Now we know the perimeter of one time around the gym, 240 ft. The next part of the problem is finding out how many times one needs to walk around the gym to walk one mile (5,280 ft.). This is a division problem. Divide 5,280 by 240 to learn how many times 240 goes into 5,280. The answer to 5,280/240 = 22. So, one needs to walk around the gym 22 times to walk one mile.

Answer 2

You must walk around the gym 22 times.
