the time taken will be 1 minute.
as first the engine of train enters and then the whole train passes and finally the last point in the train crosses the bridge.
So, total distance covered by the train = Length of bridge + it's own length
=> (200+400)m
=> 600 m.
Speed = 36 kmph = 10m/s
Hence, time taken = 600/10 s = 60s = 1min
