A Train Passes A Station Platform In 36 Sec And A Man Standing On The Platform In 20 Sec. If The Speed Of The Train Is 54 Km/hr. What Is The Length Of The Platform?

Answer»

Speed = 54 * 5/18 = 15 m/sec.

Length of the TRAIN = 15 * 20 = 300 m.

Let the length of the PLATFORM be x m . Then, 

(x + 300)/36 = 15 => x = 240 m.

Speed = 54 * 5/18 = 15 m/sec.

Length of the train = 15 * 20 = 300 m.

Let the length of the platform be x m . Then, 

(x + 300)/36 = 15 => x = 240 m.
