Answer:

240 m

Step-by-step explanation:

Train passes 36 sec but man standing 20sec so (36-20=16)

speed= 15m/sec

length=16*15=240m

Answer:

240 m

Step-by-step explanation:

Let the length of the platform be 'x' m.

Given, Speed of the train = 54 km/hr

                                          = 54 * (5/18) m/s

                                          = 15 m/s


Given that train passes man in 20 seconds.

Length of train = 15 * 20

                        = 300 m.


We know that Speed = Distance/Time

⇒ 15 = (x + 300)/36

⇒ 36 * 15 =x +300

⇒ 540 = x + 300

⇒ 240 = x.


Therefore, the length of the platform = 240 m.


Hope it helps!
