Problems on Trains - Data Intensity 1 Questions and Answers Discussion Page.

7.	Two trains of equal length are running on parallel lines in the same direction at 46 km/hr and 36 km/hr. The faster train passes the slower train in 36 seconds. The length of each train is?
	A.	50 m
	B.	72 m
	C.	80 m
	D.	82 m

Answer: Option A

Explanation:

Let the length of each train be x metres.

Then, distance covered = 2x metres.

Relative speed = (46 - 36) km/hr

=		10 x	5	m/sec
			18

=		25	m/sec
		9

	2x	=	25
	36		9

2x = 100

x = 50.
