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.
