When a train passes a point object (like a man or a pole), the distance covered is equal to the length of the train. When a train passes an extended object (like a bridge or platform), the distance covered is equal to the length of the train plus the length of the object. Speed = Distance / Time.
A man standing near a railway track observes that a train passes him in 80 seconds but to pass by a 180 m long bridge, the same train takes 200 seconds. What is the speed of the train?
