Question

Wo train each 500 m long, are running in opposite directions on parallel tracks. if their speeds are 45 km/hr. and 30 km/hr. respectively, the time taken by the slower train to pass the driver of the faster one is

Answer 1

Hii..
Here is your answer..

Solution:-
Relative speed =(45+30)
=>75km/h
In order to change it into m/s we'll multiple it by 5/18
$= > 75 \times \frac{5}{18} \\ = > \frac{125}{6} m \: per \: sec$
Now,
We have find the Time taken by slower train to pass the driver of the faster train.

Hence,
Distance covered=Length of slower train
=>500m

Required time=
$= > 500 \times \frac{6}{125} \\ = > 24seconds$
Hope it helps uh...✌️✌️✌️
