    0.25m/s2

    Explanation:

    Acceleration is simply the change in velocity per unit time. It is expressed mathematically as:

    Acceleration (a) = change in velocity (ΔV) / time (t)

    a = ΔV/t

    Data obtained from the question include:

    Change in velocity (ΔV) = 20 m/s

    Time (t) = 80 secs

    Acceleration (a) =.?

    Applying the equation a = ΔV/t, the acceleration of the bus can be obtained as follow:

    a = ΔV/t

    a = 20/80

    a = 0.25m/s2

    Therefore, the acceleration of the bus is 0.25m/s2
