Question 566204
How many revolutions will a car wheel of diameter 24 in. make as the car travels a distance of one mile?
**
For each revolution the wheel makes, the car travels the circumference of the wheel=
2π*radius=π*diameter=24π in.
One mile=5280 ft*12 in/ft=12*5280 in
So, for one mile the wheel will make 12*5280/24π=2640/π≈840 revolutions
