Two trains travelling in the same direction at 40 kmph and 22 kmph completely pass each other in 1 minutes. If the length of first train is 125 m, what is the length of second train ?  Select:	A) 125 m	B) 150m	C) 175 m	D) 200m	E) none of these
Let the length of the second train be X.   Speed of both the trains = (40 - 22) x 5/18 = 5 m/s   Thus, (125 + X)/5 = 60 sec   or, 125 + X = 300   or, X = 175m   ANSWER:175 m
