Correct Answer - Option 2 : 216 kmph
Given:
Length of the train = 200m
Length of the bridge crossed = 160m
Time taken to cross the bridge = 6 seconds
Concept used:
A train is considered crossing a bridge/platform when its total length along with the length of the bridge/platform is covered by the train
Detailed solution:
Speed of the train = Distance covered/Time taken
⇒ Speed = 360/6
⇒ Speed = 60 m/sec
Now, in kmph
⇒ 60 × (18/5)
⇒ 18 ×12
⇒ 216
∴ The speed of the train is 216 km/hr
