    Answer:

    The man covers 200 ft in 40 seconds.

    Step-by-step explanation:

    A person is moving on the sidewalk from one end to the other end.

    He walks 40 feet in 8 seconds.

    Therefore his speed = \frac{distance covered}{time}

                                       = \frac{40}{8}

                                       = 5 ft/s^{2}

    He covers the sidewalk distance at a rate of 5 feet every second.

    To calculate the time taken to cover 200 ft,

    time = \frac{distance to be covered}{speed}

    time =\frac{200}{5}

    time  = 40 seconds

    Hence the man covers 200 ft in 40 seconds.
