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

Answer»

SPEED = 54 x5/18 m/sec = 15 m/sec.

Length of the train = (15 x 20)m = 300 m.

LET the length of the platform be x METRES.

Then,x + 300/36 = 15

 x + 300 = 540

 x = 240 m.

Speed = 54 x5/18 m/sec = 15 m/sec.

Length of the train = (15 x 20)m = 300 m.

Let the length of the platform be x metres.

Then,x + 300/36 = 15

 x + 300 = 540

 x = 240 m.
