Answer 1

A train speeds past a pole in 15 seconds and a platform 100 m long in 25 ... Letthelengthofthe trainbexmetresanditsspeedbyym/secThen

Answer 2

Answer:

150

Step-by-step explanation:

Let the length of the train be x metres.

And its speed by m/sec.

Then, x/y = 15 => y = x/15

x + 100/25 = x/25

=> 15(x + 100) = 25x

=> 15x + 1500 = 25x

=> 1500 = 10x

=> x = 150
