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.
Explanation: Therefore 108 kph is the answer

Answer: 30m/s
Explanation:
Length of bridge= 200m
Length of train= 100m
Total time taken= 10s
Total distance covered= 100m+200m
=300m.
Speed of train= Distance/Time
V=S/T
V= 300m/10s
V= 30m/s.
Already explained in the image.
