Two trains running at the rate of 75km and 60km an hour respectively on parallel rails in opposites directions, are observed to pass each other in 8 seconds and when they are running in the same direction at the same rates as before, a person sitting in the faster train observes that he passes the other in 33 seconds. Find the lengths of the trains.
Relative speed white running in opposite direction 12
Again, relative speed while running in same direction
As we know, velocity =
Lengths of the both trains = meter
Now, as the faster train exceeds the slower train in the same direction in seconds.
The length of the slower train = meter.
The length of the faster train = meter
(ans.) Faster train 168.75 meter & slower train 131.25 meter.
