A train leaves Delhi at 6.00 a.m. and reaches Agra at 10.00 a.m. Another train leaves Agra at 8.00 a.m. and reaches Delhi at 11.30 a.m. At what time do the two trains cross each other if the distance between Delhi and Agra is 200 km?

Speed of first=s=200/4=50km/h
Speed of second=S=200/3.5=400/7km/h
Till 8 A.M. first one has already covered 50 x 2=100 Kms
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=14x60/15=56 minutes
So they will cross each other at 8.56A.M
