Question
why is the total distance traveled by a mass traveling in a circle of radius R during n revolutions =2piRn. The average speed is the distance traveled divided by the elapsed time, so:
v=2piRn/delta T, where delta T is the elapsed time.
v=2piRn/delta T, where delta T is the elapsed time.

Why?
the distance around the circle once is 2PI*radius. If one goes n times around, then total distance is 2PI*radius*n
and of course, avgspeed is total distance/time.
