Answer:
Given Train starts at the same time.
Hence, Time remains constant.
Speed of Train 'T1' be 'S1' = 40 km\hr
Speed of Train 'T2' be 'S2' = 45 km\hr
Let X be the distance at which trains meet.
Train T2 travels X+40 km more than Train T1
According to the formula.
Speed=
Time
Distance
Time=
45
X+40
Time=
40
X
From above two equations.
40
X
=
45
X+40
45×X=40×X+40×40
5×X=1600
=320 km
Distance between two Stations = Distance at which train T1 meet + Distance at which Train T2 meet + Distance train T2 travels
= 320+320+40
= 680
