A train of ‘x’ metres running at the speed of 72 km/hr takes 12.1 seconds to completely pass over a bridge that is 132 metres long. What is the value of ‘x’?
Question
Solution 1
Step 1: Convert the speed from km/hr to m/s. We know that 1 km/hr = 5/18 m/s. So, 72 km/hr = 72 * (5/18) = 20 m/s.
Step 2: The total distance covered by the train to completely pass the bridge is the length of the train plus the length of the bridge. This distance is covered in 12.1 seconds. So, we Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
