Question

a train 250 m long passes a pole in 12.5 sec.how long it will take to pass a platform of 500 m long?​

Answer 1

Answer:

as for 250m it takes 12.5 seconds

so for 500 metre it will take the twice of 250 (as 500=2*250)

so time taken by train to pass 500 m platform would be

2x12.5

that is 25 seconds

Answer 2

Answer:

is 25 sec

Step-by-step explanation:


Since the dist. For pole is half the dist of platform, so we will double the dist of platform i.e. 250x2= 500m
Since the dist is doubled so we will double the time also
T.= 12.5x2
= 25 sec
