if the tires of a vehicle are rotating 100 times per minute, with a radius of 1 1/2 ft, how fast is the vehicle moving?

Question

I really don't know how to do this? help

Answer 1

The distance traveled when the tire rotates one time is the circumference of the tire, which is give by the equation

c = 2πr                  [2 * pi * radius]

 

How far does the car travel when the tires rotate one time?

 

How far does the car travel when the tires rotate 100 times?

 

The tires rotate 100 times per minute, for 60 minutes in one hour, how far (in feet) will the car travel?

 

There are 5280 feet in one mile, so how many miles will the car travel in one hour?

 

 

Answer that last question as miles per hour to get how fast the vehicle is moving.
