Bajinder runs ten times around a squaretrack and covers 4km. Find the length of the track.
Given:
Number of times Bajinder run = ten times
Distance covered = 4 km
Solution:
Distance covered in one round = 4000 / 10
= 400 m
Perimeter of track = Distance covered in one round
4 × side = 400
Length of side = 100 m.
