Question

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

Answer 1

UIf athele covers 200 meter in 40second in a circular path then he will cover three and a half round in 2 minutes 20 seconds
Total distance =circumference =2 pi r
2 ×22/7×100meters =4400/7meters
Displacement = diameter of the circular path =200 meter
