Two trains, each 100 m long, moving in opposite directions, cross each other in 8 s. If one is moving twice as fast the other, then the speed of the faster train is
Let the speed of the slower train be x m/s.
Then, the speed of the faster train = 2x m/s.
Relative speed = (x + 2x) m/s = 3x m/s.
⇒ 24x = 200
So, speed of the faster train = `50/3`m/s
