    Answer:

    0.56 m/s

    Step-by-step explanation:

    The average speed of a body tells how fast is the body moving; it is calculated as:

    v=\frac{d}{t}

    where

    d is the distance covered

    t is the time elapsed

    In this problem, we don’t know the distance covered by Ben. Therefore, we will assume that it is 1 km:

    d = 1 km = 1000 m

    The time elapsed to cover this distance is:

    t=30 min \cdot 60 =1800 s

    Therefore, Ben’s average speed is:

    v=\frac{1000}{1800}=0.56 m/s
