    3.33m/s

    Explanation:

    The total distance that he runs is

    30m north + 30m south + 40m north = 100 m

    If the entire run takes 30 seconds then the average speed is distance over a unit of time

    100 / 30 = 3.33 m/s

    You can draw a sketch of a line going north 2 spaces, then going south by 3 spaces, finally going north again by 4 spaces
