Answer:
The bridge is 200 m long and the train is 100 m long. Therefore, the entire train must travel 300 m to clear the bridge and it does so in 10 sec. So its speed is 300 m per 10 sec or 30 m per sec or 108 km/hr.

The train is said to be travelling at a uniform speed - meaning you can pick any section of the journey to calculate its speed.
Speed = distance / time
Speed = 200m / 10 secs
= 20 m/s
20m/s to km/hr = 20 × 18/5 = 72km/hr
The train is travelling at a speed of 72km/hr or 20m/s
