what is the length of train A?
the length of B is 2 length of A
B = 2*A
This is not a correct way of solving this problem You have to find the length of A
The length of B is 2 times of A is the answer
@abhishek587 when are you going to write the correct solution for this question?
(velocity of train A) x 40 seconds = length of train B
40 times the speed of train A in m/s.
You need to give one more figure either speed or length of train A to know the exact length of train B in meters
bhai this quetion is ask in bank peo exam qution shai ha
You have to give the length of the train A in order to find length of train B.
Cause by that way we can calculate the speed of it.
Or give the Speed of it
Bro first find the length of train A by relativespeed and speed fourma
But what is the question ?
This is question a train A crosses a stationary train B in 60 second and a pole in 20 second with the same speed the length of the train B(in meter) ?
to find length of train b
considering speed as 1m/s
then length of train B is 40m
