Answer:
280,0
Explanation:
distance travelled means the total distance travelled by athlete whereas displacement means the shortest distance between two points.
therefore,distance travelled by athlete is 2*perimeter of rectangle
=2*[2*(l+b)]
=2*[2*(50+20)]
=280m
and the displacement is zero because he reached the starting point,so distance between starting and ending points is zero
