Description: A 100-meter long train crosses a 200-meter long and 20-meter wide bridge in 20 seconds. What is the speed of the train in Km/hour?

Solution

We will only consider length of bridge
Now total distance = 100+200 = 300m
Now time taken to cross = 20 seconds
Therefore speed = 15m/sec = 15(18/5) = 54km/hr
