distance covered = 1/2×2×22/7×100
=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
