A goods train runs at the speed of 72 kmph and crosses a 250 m long platform in 26 seconds. What is the length of the goods train?

We are given the following:

• Speed of the goods train = 72 km/h
• Time taken to cross the platform = 26 seconds
• Length of the platform = 250 m

Step 1: Convert the speed from km/h to m/s
We know: 1 km/h = (1000 / 3600) m/s Speed = 72 × (1000 / 3600) Speed = 72 × (5 / 18) Speed = 20 m/s

Step 2: Calculate the total distance covered while crossing the platform
Formula: Distance = Speed × Time Distance = 20 m/s × 26 s Distance = 520 meters

Step 3: Subtract the length of the platform to find the length of the train
Train Length = Total Distance - Platform Length Train Length = 520 m - 250 m Train Length = 270 meters

Final Answer:
The length of the goods train is 270 meters
