    Answer:

    6.25 m/s

    Explanation:

    The average speed of an object is the ratio of the total distance traveled by the object and the total time taken to cover the distance. Mathematically,

    Average speed = total distance traveled/total time taken.

    In this case;

    Total distance traveled = 650 + 850 = 1500 m

    Total time = 240 s

    Average speed = 1500/240 = 6.25 m/s

    The average speed of the man is, therefore, 6.25 m/s.
