let both trains meet at x distance from station A
TRAIN 1
distance = x
speed= 35
time = x/35
TRAIN 2
distance = 315-x
speed = 28
time = 315-x/28
the time when they meet will be equal
x/35 = 315-x/28
x/5 = 315-x/4
4x = 1575 - 5x
9x = 1575
x = 175
& t = x/35
= 175/35
= 25/5
=5
Therefore the trains will meet at 175 km apart from station A and after 5 hrs.

1st train =35 km per hour
2nd train = 28 km per hour
35 × 8 = 280
28 × 10 = 280
2nd train = 28 km per hour
35 × 8 = 280
28 × 10 = 280
