Question
A train running at the speed of 60 km/hr crosses a pole in 9 seconds. What is the length of the train?
Solution
Sure, here is the step by step solution:
Step 1: Convert the speed from km/hr to m/s. We know that 1 km/hr = 5/18 m/s. So, 60 km/hr = 60 * (5/18) = 16.67 m/s.
Step 2: The time taken to cross the pole is given as 9 seconds.
Step 3: The length of the train can be found by multiplying the speed of the train by the time taken to cross. This is because Speed = Distance/Time, which implies that Distance = Speed * Time.
Step 4: Therefore, the length of the train = Speed * Time = 16.67 m/s * 9 s = 150.03 m.
So, the length of the train is approximately 150 meters.
