A train running at the speed of 60 km/hr crosses a pole in 9 seconds. What is the length of the train?

Step 1: Understand the given information

• Speed of the train = 60 km/h
• Time taken to cross a pole = 9 seconds
• When a train crosses a pole, it covers a distance equal to its own length.

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.
