2 trains are moving in the same direction at 65 km/hr. and 45 km/hr. The faster train crosses a women in slower train in 8 seconds. What is the length of the faster train?

two trains are moving in the same direction at 45kmph & 25 kmph. the faster train crosses the passenger travelling in the slower one in 18 second.the length of faster train is

The trains are moving in the same direction. So,
Relative speed = 65 - 45 = 20 kmph = (20 *5/18) = 50/9 m/sec.
In 8 seconds, faster train crosses its own length i.e. it travels its own length.
So, Length of the train ( distance traveled by train in 8 sec),
= Speed * time
= (50/9) * 8
= 44.44 m.
Length of the faster tarin = 44.44 m.
