    Answer: 53.33 km/hr

    Step-by-step explanation:

    The total distance covered by car is 80 KM (40+40).

    Now their are two cases:

    Case 1) Distance covered 40km, speed 80km/h. Now we all know speed=Distance / time

    So Time taken is 0.5 hour.

    Case 2) Now again distance covered is 40 km but speed is 40Km/h

    So time taken is 1 hr

    Now total distance traveled is 80KM. Total time taken is 1.5 hrs (0.5+1)

    Average speed = Total Distance/Total Time

    Average Speed = 80/1.5

    Which is equal to 53.33km/h
