A train has a length of 150 meters.It is passing a man who is moving at 2km/hr in the same direction of the train in 3 seconds.Find out the speed of the train?

To find the speed of the train, we can use the formula for relative speed and the distance it covers. 1. The distance covered by the train is equal to its length, which is 150 meters. 2. The time taken to pass the man is 3 seconds. Using the formula: Speed = Distance / Time, the speed of the train relative to the man is: Speed = 150 meters / 3 seconds = 50 meters per second. Now we need to convert the man's speed to meters per second: 2 km/hr = (2 * 1000) / (3600) = 0.5556 meters per second (approximately). The speed of the train can be found by adding the man's speed to the relative speed: Speed of the train = 50 m/s + 0.5556 m/s = 50.5556 m/s. Converting this speed back to km/hr: (50.5556 * 3600) / 1000 = 182 km/hr (approximately). So, the speed of the train is approximately 182 km/hr.
