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.
