A train travels from City A to City B, a distance of 720 miles, at a constant speed of 60 miles per hour. On the return trip, due to maintenance work on the tracks, the train travels at 40 miles per hour. What is the average speed for the entire round trip?

**How to Calculate Average Speed for a Round Trip: A Train Journey from City A to City B** Have you ever wondered how travel times factor into daily commutes, weekend getaways, or even freight logistics? For many, the story of a train journey—like one traveling 720 miles between two major cities at 60 mph forth and 40 mph return due to track maintenance—sparks natural questions about timing and efficiency. This isn’t just a math puzzle; it’s a real-world scenario shaping how we understand travel, cost, and infrastructure across the U.S. Understanding the true average speed for this round trip isn’t only about numbers—it’s about context: delays impact schedules, fuel use, and economic planning. The calculated average speed reveals how much time train operators save during maintenance windows and highlights the variability in travel routines. With modern travel increasingly driven by precision and transparency, mastering these calculations empowers better decision-making, whether choosing rail options or assessing regional transit reliability. **Plugging in the Numbers: The Classic Distance-Speed-Average Speed Puzzle**
