Answer:

Average Speed = 45km/h

Explanation:

Case1_

distance travelled = speed × time

=40×2

=80km.

Case2_

distance travelled=speed×time=50×2=100km.

NOW,

Total distance travelled = 80km+100km=180km.

Total Time taken=2hours+2hours=4hours.

Therefore, average speed =

(Total distance travelled)÷(Total time taken)

=180÷4

=45km/h (Answer)
