Title: Average Speed of a Round-Trip Train Journey: Train Travels 300 km Between City A and City B When analyzing train travel efficiency, one of the most commonly asked questions is: What is the average speed for the entire journey? In this detailed article, we explore a real-world scenario: a train traveling between two cities — City A and City B, a distance of 300 km — at different speeds on the outbound and return trips. Understanding how to calculate the average speed for this round trip sheds light on travel time efficiency and transport planning. ### The Journey in Detail - Outbound Trip:
The train travels 300 km from City A to City B at a speed of 100 km/h.
Time taken = Distance ÷ Speed = 300 km ÷ 100 km/h = 3 hours.
