Shouldn't it be 650+(240*2)?

Here train passing both the pole as well as the plate form ....
in question they clearly mentioned pole passing time in seconds only......
so we have to solve first 240/24 =10sec..
and than
(240+650/10)=890/10=89 sec.......

They are asking 650 only know. Then why we are adding 240+650.

Length of platform = 640m
and entire train length = 240m
the Q. is we have to find time taken by train to pass entire platform.
so we include train length utill its last coach passing the platform.
time considered up to its last coach left the platform.
ok.

We add both of them because we have to calculate the time taken to cross the platform. 240 is the length of train. So total distance, the engine has to cover is 240 (train length) + 650 (platform length).
