    Answer:

    1.27 m/s.

    Explanation:

    The following data were obtained from the question:

    Displacement (D) = 28 m

    Time (t) = 22 secs

    Velocity (v) =?

    Velocity is simply defined as the rate of change of displacement of an object with time. It can be represented mathematically as:

    Velocity (v) = Displacement (D) /Time (t)

    v = D/t

    With the above formula, we can obtain the swimmer’s velocity as follow:

    Displacement (D) = 28 m

    Time (t) = 22 secs

    Velocity (v) =?

    v = D/t

    v = 28/22

    v = 1.27 m/s

    Therefore, the swimmer’s velocity is 1.27 m/s.
