Question

Another train left agra at 8 am and reaches agra at
11.30 am. If the distance between them is 200 km
then on what time trains will meet?​

Answer 1

Hey Mate,

Here is your answer:

Speed of first train= s= 200/4= 50 km/h

Speed of second train= S= 200/3.5= 400/7 km/h

Till 8 A.M. first one has already covered 50 x 2= 100 Km s

So now both are 100 km apart

They are approaching each other

So relative speed= 50+400/7= 750/7 Km/h

Time= 100/(750/7)= 700/750= 14/15 hours= 14 x 60/15=56 minutes

So both the trains will meet at 8.56 A.M

Thank you........
