Question

A traln speeds past a pole and a 100-metre-long platform in 15 seconds and 30 seconds respectively. Find the
length of the train In metre​

Answer 1

Answer:

The answer is 150 m.

Step-by-step explanation:

Let the length of the train is x meter and Speed of the train is y meter/second.

Then x/y = 15

=> y = x/15(speed of train)

a/q

(100+x)/25=x/15

=>x=150 m

hope it helps you

Answer 2

Let the length of the train be x metres and its speed be y m/sec.

Then, (x/y)= 15   y =(x/15)

(x+100)/25 = x/15

=> 15(x + 100) = 25x

=> 15x + 1500 = 25x

=> 1500 = 10x

=> x = 150 m.

So, the length of the train is 150 metres
