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

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

To calculate the length of the train, we can use the formula:

Length of the train = Speed x Time

Given that the speed of the train is 60 km/hr and the time it takes to cross a pole is 9 seconds, we need to convert the speed to meters per second before applying the formula.

1 kilometer = 1000 meters 1 hour = 3600 seconds

So, the speed of the train in meters per second is:

60 km/hr = (60 * 1000) meters / (3600 seconds) = 16.67 meters/second (approximately)

Now, we can calculate the length of the train:

Length of the train = Speed x Time Length of the train = 16.67 m/s x 9 s = 150 meters

Therefore, the length of the train is 150 meters.
