Two Trains Are Running With The Speed Of 60 Km/hr And 40 Km/hr Respectively In The Same Direction. The Fast Moving Train Completely Passes A Man Sitting In Slower Train In 9 Sec. Find The Length Of The Fast Moving Train?

Answer»

RELATIVE SPEED of both TRAIN = (60-40) km/hr = 20 km/hr

20km/hr= 20*(5/18) m/sec = 100/18m/sec

So the length of fast moving train= (100/18)*9= 50m.

Relative speed of both train = (60-40) km/hr = 20 km/hr

20km/hr= 20*(5/18) m/sec = 100/18m/sec

So the length of fast moving train= (100/18)*9= 50m.
