Two trains are running in opposite directions with the same speed. If the length of each train is 60 m and they cross each other in 12 sec, then the speed of each train is?
Pick one
A) 30 B) 35 C) 18 D) 12 E) 38
Let the speed of each train be x m/sec.   Then, relative speed of the two trains = 2x m/sec.   So, 2x = (60 + 60)/12 =&gt; x = 5   Speed of each train = 10 m/sec.   = 5 * 18/5=
