Can we add 650+240+240? Because the train crosses between the two ends of the platform.

240 m passes in 24 sec.
1 m passes in 24/240.
890 m passes in 24 * 890/240 = 89 sec.
1 m passes in 24/240.
890 m passes in 24 * 890/240 = 89 sec.

240m=24sec.
890m=?
Train length+platform length=240+650=890m.
=24*890/240.
=89.
890m=?
Train length+platform length=240+650=890m.
=24*890/240.
=89.

I think in question ask the time taken for only bridge 650. Then why we add both?

No. It not pass poles and platform. It pass only platform. 240m is train length.

Speed = total (distance/time).
240/24sec = 10 ms.
So, 650/10ms = 65 sec.
240/24sec = 10 ms.
So, 650/10ms = 65 sec.

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