Question

Walking 3/4 of his usual speed, a peon is 10 minutes too late to his office. Find the usual time to cover the distance.

Answer 1

Let his initial speed be y ms^-1.

And distance = d m

Given :

(usual time) × (y) = d

(usual time + 600s) × (3/4) × (y) = d

Therefore,

(usual time) × (y) = (usual time + 600s) × (3/4) × (y)

Let usual time be t.

t = 3( t + 600)/4

4t = 3t + 1800s

t= 1800s = 30 minutes.

Do it usually takes 30 minutes for the peon to reach his office.
