The Circumference of a wheel 1.1m dia is 1.1*pi Thus 2000/(1.1*pi) is the number of turns the wheel will make. 2000/3.456 = 578.7 revolutions to one decimal place (pi assumed to be 3.14159)
That completely depends on the size of the wheel ... the rear wheel on a farm tractor wouldn't turn as many times in 1 mile as the wheel on a skateboard would. If the tire on a car is 30 inches across, then it turns 672 revolutions (rounded number) in one mile.

The quickest way is to jack up the rear of the car or truck and turn the rear wheel 1 complete turn and see how many revolutions your pinion yoke turns. if it makes thee revolutions and a little over it could be a 308 four turns and a little over would be a 410 ect..
There are 60 seconds in a Minute. RPM is revolutions per Minute. So your question answers itself.
The propeller turns many revolutions per minute and deflects air behind it .
