    Answer;

    Average speed = 47.5 km/hr

    Explanation and solution;

    Average Speed = Total distance / Total time

    Total distance;

    -In the first two hours travelling at 40km/hr, total distance traveled is 80km.

    (40 * 2) = 80 km

    -In next two hours distance covered is 110 km. (55 * 2)

    Total distance = 110 + 80 = 190 km

    Total time = 2 + 2 = 4 hours

    Average Speed = Total distance / Total time

    = 190/4

    = 47.5 km/hr
