What is the number of revolutions turned by a typical automobile on a yearly basis?
jerkstoreowner asked:
Determine the number of revolutions through which a typical automobile tire turns in 1 yr. Suppose the automobile travels 11000 miles each year on tires with radius 0.220 m.

??? revolutions
I would appreciate any help. Please show me how to solve it in detail, I learn best that way!

I would ventue that there are x revolutions by number 11000 miles fjw75 fjw75

Distance/revolution = Circumference of tire = 2πR = 6.28(0.220) = 1.38 m
Total Distance = 11,000 miles = 1609 m/mile x 11,000 = 17,699,000 m
Total Distance/Distance per revolution = 17,699,000/1.38 = 1.28e7 revolutions ANS Jim
