Length of train is 170 meters and speed of train is 63 km/hour. This train can pass a bridge in 30 seconds, then find the length of the bridge.

335 mts

325 mts

365 mts

312 mts

Given speed = 63 km/hr = 63 × 5/18 = 352m/s

Let the length of the bridge = x mts

Given time taken to cover the distance of (170 + x)mts is 30 sec.

We know speed = distance/time m/s

35/2 = 170+x /30

x = 355 mts.

Hence, option 1 is the correct answer.
