Answer:
Let the trains be A and B.
A's speed = 60- Km/ h
B's speed = 75- Km/ h
At 10.30. the trains A and B are 30- Km apart.[ ½- travel of Train A] .
The relative Speed of both trains is [75-60 ] =15- Km/ h.
So to cover a distance of 30- Kms, they had to travel = 30/15 = 2- hours.
Therefore the the TWO TRAINS WILL MEET AT (10.30+2.00)= 12.30- P.M.
The distance at which they will meet will be (75 x 2)= 150- Kms from KANPUR.
