A train travels between two stations. The train will be on time if it runs at an average speed of 60 km/hour, but will be late by 5 minutes if it runs at an average speed of 50 km/hour. What is the distance between the two stations?

Answers (1)
S safeer

Let the distance between the station be d

Given 

t=d/60......(1)

t-5/60=d/50....(2)

Substituting the value of from equation (1) to equation (2)

d/60 -5/60=d/50

d/60-d/50=5/60

-d/300=5/60

d=-25 Km

d cannot be negative. 

|d|=25Km
