Two trains of equal are running on parallel lines in the same direction at 44 km/hr and 36 km/hr. The faster train passes the slower train in 36 sec. The length of each train is? Choose the correct choice from the following choices:	A) 40 m	B) 72 m	C) 80 m	D) 82 m	E) 84 m
Let the length of each train be x m.   Then, distance covered = 2x m.   Relative speed = 44 - 36=

8 km/hr.= 8 * 5/18 = 20/9 m/sec.   2x/36 = 20/9 =&gt; x = 40.   40 mNSWER:40 m
