Two trains are running in opposite directions with the same speed. If the length of each train is 360 m and they cross each other in 12 sec, then the speed of each train is?	Choose the correct choice from the following answers:
A) 11  B) 27  C) 36  D) 99  E) 108
Let the speed of each train be x m/sec.   Then, relative speed of the two trains = 2x m/sec.   So, 2x = (360 + 360)/12 =&gt; x = 30   Speed of each train = 10 m/sec.   = 30 * 18/5=
