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 24 sec, then the speed of each train is?  Select the correct option.
A) 78  B) 89  C) 36  D) 54  E) 23
Let the speed of each train be x m/sec.   Then, relative speed of the two trains = 2x m/sec.   So, 2x = (360 + 360)/24 =&gt; x =15   Speed of each train = 15 m/sec.   = 15 * 18/5=
