Task: Solve the math problems. Intermediate steps are required.
input: A train running at the speed of 36 km/hr crosses a pole in 9 seconds. what is the length of the train?
output: The speed 36 km/hr = 36 x 1000 / 3600 m/s = 10 m/s. 
The length of the train = speed x time = 10 x 9 = 90 m.
So, the length of the train is 90 meters.
