The body changed position, from one side of the circle, to the other.
displacement=changeposition/time=2PIr/20
there has to be a direction associated with displacement, my drawing has it West.
average speed: distance/time=2PIr/20
average velocity: 2PIr/20 West
displacement=changeposition/time=2PIr/20
