Answer:

average speed-20/9 kmph or 8m/s.

average velocity-0

Explanation:

average speed-here the distances are equal,we have the formula of finding average speed when distance is equal as V1*V2/V1+V2.if we substitute the values here    we get 50*40/50+40 which gives 200/90=20/9 kmph which when converted into m/s gives 8.

average velocity-as the car came to the same position the displacement is 0 so the average velocity will be 0.
