  1. Answer:

    40 sec

    Step-by-step explanation:

    5m = 500 cm in 1 sec

    60m = 6000 cm

    it falls down 200 cm over next 1 sec

    distance it covers in 2 sec= 500-200cm = 300cm

    time taken to cover 300cm = 2 sec

    time taken to cover 1 cm = 2sec/300cm

    time taken to cover 6000cm

    = 2sec/300cm×6000cm

    = 40 sec
