Question

An athlete completes one round of a circular track of diameter 200 m in 40 s what will be the distance covered and the displacement at the end of 2 minutes 20 s ​​

Answer 1

Answer:

time taken to complete one round=40sec

total time =20mon20sec =2×60+20 sec

=140sec

no. of rounds completed=140/40 =3.5

distance covered=2πr×3.5

=2×22/7×200\2×3.5

=2200m

if athlete starts from the point A, then after 3.5 athlete will be on the point B.

therefore,

displacement will be= AB =200m..
