Question

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

Answer 1

speed=distance upon time
so thefore distance =speed into time
applying this solve the problem

Answer 2

Hi friend,

# 200M

Solution :
Time taken = 2 mins 20 sec = 140 sec

Radius = 100 m

In time to complete one round 40 sec so, round completed in 140 = 140÷40 = 3.5 meter

Distence cover = 2× 22/7 × 100 × 3.5 = 2200 m

Thus at the end, the athlete covers half round and will be at a distance = diamiter of a circle. i.e. displacment is 200m..i hope it helps you
