Solution for yesterday’s problem

Conventional method

Let ‘t’ be the usual time in minutes

By supposition, 30(t+10)=42(t-10)

=>t=60 minutes

In 60 minutes the man travels 30 km. Therefore, in 70 minutes he will travel 35 km which is the distance he covers to reach the destination.

Other method 1

(30*10+42*10)/(42-30)=60 minutes (usual time)

Other method 2


=>d=35 km
