    Answer: 0.13m/s^2

    Explanation:

    Formula: a=\frac{V_2-V_1}{t}

    Where;

    a = acceleration

    V2 = final velocity

    V1 = initial velocity

    t = time

    If John runs 1.0 m/s first, we assume this is V1. He accelerates to 1.6 m/s; this is V2.

    a=\frac{1.6m/s-1.0m/s}{4.5s}

    a=\frac{0.6m/s}{4.5s}

    a=0.13m/s^2
