Two trains, each 100 m long are moving in opposite directions. They cross each other in 8 seconds.

Two trains, each 100 m long are moving in opposite directions. They cross each other in 8 seconds. If one is moving twice as fast the other, the speed of the faster train is

Let the speed of the slower train be x m/sec.Then, speed of the faster train = 2x m/sec.Relative speed = (x + 2x) m/sec = 3x m/sec.(100 + 100)8 =3x 24x = 200x = 25.3So, speed of the faster...
