  1. Answer:

    Time taken = 2 min 20sec = 140sec.

    Radius r = 100m.

    In 40 sec the athlete complete one round.

    So, in 140sec the athlete in 140sec = (2 π r) x(3.5) = 2x (22/7) x 100x 3.5=2200m.

    At the end of his motion, the athlete will be in the diametrically opposite position.

    Displacement = diameter =200m

    Explanation:

    Hope it is helpful for you please make me a brain list
