Correct Answer: 270 m
Explanation:
Step 1: Understand the given data
Step 2: Convert speed to meters/second
Speed in m/s = 72 × (5/18) = 20 m/s
Step 3: Calculate total distance covered in 26 seconds
Distance = Speed × Time = 20 × 26 = 520 meters
Step 4: Find the length of the train
Total distance covered includes the train and the platform:
Length of train = Total distance - Length of platform Length of train = 520 - 250 = 270 meters
Answer: 270 meters
The length of the goods train is 270 meters.
This problem illustrates a key concept in speed and distance calculations, where the total distance covered by the train while crossing a platform is the sum of its own length and the length of the platform.
