    Explanation:

    Hey, there!!

    Here,

    speed (s)= 20m/s

    distance (d)= 1km

    = 1000m

    now,

    we have formula,

    t = \frac{d}{s}

    putting value,

    t = \frac{1000m}{20m/ s }

    cancelling the like terms,

    t = 50s

    Therefore, the time is 50s.

    Hope it helps...
