Answer:
m=217 miles/31 days
Step-by-step explanation:
Carl has to run 217 miles in 31 days; to find the number of miles he needs to run per day, he should divide the number of miles he has to run (217 miles ) by the number to days he will run ( 31 days):
Carl has to run 7 miles per day. We can confirm this result by multiplying this by 31 days, and we should get 217 miles:
If we were to put a distinguishing mark on a specific random place on the tire, right at the point where the tire meets the ground for example, when the car starts moving, the tire has made one full revolution when that same mark meets the ground again. That is also known as the circumference of a circle...one time around the circle. The formula for the circumference of a circle is
.
We are given a radius of 13 inches and are told to use 3.14 for pi. That means that our formula looks like this:
and C = 81.6 inches, That's how far the tire travels every time it turns exactly once.
