Answer 1

Answer:

300 m

Step-by-step explanation:

Given  

if a train passes an electric pole in 30 seconds and passes a platform of length 200 m in 50 seconds, the length of the train is  

ANSWER

Let the length of the train be x metre.

So speed of the train will be

X / 30 = x + 200 / 50

50 x = 30 (x + 200)

50 x = 30 x + 6000

20 x = 6000

X = 6000 / 20

X = 300 m

So length of the train is 300 m.
