Title: Understanding Average Speed: A Train Journey Analyzed When planning a train journey, one common question arises: what is the average speed over the entire route? Consider a realistic scenario: a train travels 300 kilometers at a speed of 100 km/h, then continues another 200 kilometers at 80 km/h. What is the average speed for the full trip? ### How to Calculate Average Speed Average speed is not simply the arithmetic mean of the two speeds. Instead, it measures total distance divided by total time. This approach captures the actual energy and time investment throughout the journey.
