240=24sec.
then 650=x.
240x=650*24,
240x/240=650*24/240,
= 65m/s.
then 650=x.
240x=650*24,
240x/240=650*24/240,
= 65m/s.

650/240=x/24 and x=65sec then total time is 65sec +24sec=89sec.

Why we are adding the time of poles with the time of platforms?

The train is 240 m long. Therefore we add (650+240) together.

I think we don't need to add both the meters of the platform.

I think 65 is the correct answer.
And why we add 240 +650?
And why we add 240 +650?

Why you didn't add twice the length of the platform?
