Two trains are running in opposite directions with the same speed. If the length of each train is 225 m and they cross each other in 18 sec, then the speed of each train is?	Answers:
A) 22
B) 77
C) 36
D) 88
E) 45
Let the speed of each train be x m/sec.   Then, relative speed of the two trains = 2x m/sec.   So, 2x = (225 + 225)/18 =&gt; x = 25/2   Speed of each train = 25/2 m/sec.   = 25/2 * 18/5 =- 45 km/hr.Answer: 45
