an athlete completes one round of a circular track of diameter 200m in 40 sec. What will be the distance covered and the displacement at the end of 140s?

distance covered = 1/2×2×22/7×100
=22/7×100
=314m (approx.)
displacement=200m
=22/7×100
=314m (approx.)
displacement=200m

displacement = 200
distance = 110000
displacement at the end of each 40 seconds is 0
after 120 seconds the athlete runs for another 20 seconds to rach the other end of the circular track
here displacement will be the shortest distance = diameter = 200 meter
distance at the end of each 40 seconds is pi * r^2
so distance at the end of 140 seconds is 140/40 * pi* r^2
= 140/40 * 22/7 * 100 * 100
= 110000 meter
mark this as branliest if this helps
