To find the speed of the train, we can use the formula:
Speed = Distance / Time
In this case, the distance covered by the train is the sum of its length and the length of the platform. Let's denote the length of the platform as 'L'. Therefore, the total distance covered by the train is 180 meters (length of the train) + L.
The time taken to cross the platform is given as 18 seconds.
Plugging these values into the formula, we have:
Speed = (180 meters + L) / 18 seconds
Since the length of the platform is not provided, we cannot determine the exact speed of the train.
