Question

A train crosses a pole in 15 seconds and a 100m platform in 25 seconds, what is the lenght of the train

Answer 1

speed =distance/time taken
speed=x/15(length of train X)
Also,
speed=100+x/25
so,
x/15=100+x/25
from here finds length of train and cancel the negative values

Answer 2

Given :

• A train crosses a pole in 15 seconds and a 100m platform in 25 seconds.

ㅤㅤ

Find :

• What is the length of the train?

ㅤㅤ

Calculations :

→ Speed = 100/10

→ Speed = 10 sec

ㅤㅤ

→ Length of the train = 15 × 10

→ Length of the train = 150 m

ㅤㅤ

Therefore, 150 m is the length of the train.

ㅤㅤ

VERIFICATION :

→ 150/10

→ 15
