We have the following angular velocity:
 w = 13000 rpm
 We are going to convert to revolutions per second.
 We have then:
 w = 13000 * (1/60)
 w = 216.6666667 rev / sec
 We now multiply the angular velocity by time:
 (216.6666667) * (220)
 = 47666.66667 rev
 Rounding:
 47667 rev
 Answer:
 it did turn about 47667 rev in this time

Answer:

23833.33

Step-by-step explanation:

The first step is to find the average velocity. To do this you simply divide by two.

13000rpm/2=6500rpm

To make it easier to work with you will convert it from rpm to rps

6500rpm/60=108.33rps

Then you multiply the revolutions per second by the number of seconds to find the amount of revolutions.

108.33rps*220sec=23833.33 revolutions
