Correct Answer: 150 metres
Explanation:
Step 1: Understand the given information
Step 2: Convert the speed to meters per second
1 km/h = 5/18 m/s
So, 60 km/h = 60 × 5/18 = 16.67 m/s
Step 3: Use the formula: Distance = Speed × Time
Distance = 16.67 × 9 = 150 meters
Answer: 150 meters
The length of the train is 150 meters.
This problem checks the basic application of speed, distance, and time formula. When a train crosses a pole, it travels a distance equal to its length. Converting speed into meters per second is essential to match units and compute accurately.
