Hey there,

Average speed=Distance/Time

=Semicircle/20

=πr/20

=220/20

=11 m/s

Average velocity=Dispacement/time

=diameter/20

=140/20

=7 m/s

PLEASE MARK AS BRAINLIEST IF HELPFUL!!!

When it completes full revolution then distance will be 2 * 22/7 * R

Half revolution will be 22/7 *R

displacement will be 2R that is length of diameter.

Hope this helps
