Question

Two trains — A and B simultaneously started from Delhi 
to Agra and Agra to Delhi respectively. After reaching their 
respective destinations, they turned back towards their 
starting points and finished their journeys after reaching 
their starting stations. They met for the first time at a distance 
of 80 km away from the Delhi station and they met for the 
second time 40 km away from the Agra station. It is further 
known that during both the meetings they were travelling in 
the opposite direction. Answer the following questions:
58. What is the distance (in km) between Delhi and 
Agra?

Shiv Raj · Answer

Solved using the ratio of speed of A and B
let the total distance be d km
So,
a/b=80/d-80
a/b=d+40/2d-40
equating the above two equations and solving for d gives d=200 km

case 1 is x-80/80
case 2 is 2x-40/x+40 
eqquate them
