Answer 2

Answer:

Length of the train is 550 m.

   

Step-by-step explanation:

Given:

Length of Railway platform = 200 m

Speed of train = 54 km/h

Time taken by train to pass the platform = 50 seconds.

To find: Length of the train.

Speed of the train in m/s = $\frac{54\time1000}{3600}=15\:m/s$

let x be the length of the platform.

When train passes the platform it cover the distance of its length and platform both.

So, Total distance covered by train = 200 + x

Now, Using Speed Distance Time Formula

$Speed=\frac{Distance}{Time}$

$15=\frac{200+x}{50}$

200 + x = 750

x = 750 - 200

x = 550

Therefore, Length of the train is 550 m.
