Question:** A train travels 300 km at 60 km/h, then 200 km at 80 km/h. What is the average speed for the entire trip?
["Average Speed Calculator: Train Journey 300 km at 60 km/h Then 200 km at 80 km/h", "When planning or analyzing train travel, one common question arises: What is the average speed for the entire journey? In this article, we break down a practical example — a train traveling 300 km at 60 km/h, followed by 200 km at 80 km/h — and show how to calculate the overall average speed for the full trip.", "---", "### 🚄 Understanding Average Speed", "Average speed is defined as the total distance traveled divided by the total time taken. It reflects how fast the journey as a whole progressed, factoring in all details like speed variations.", "---", "### 🔢 Step-by-Step Breakdown", "#### Step 1: Calculate Time for Each Segment", "- First segment:\n Distance = 300 km, Speed = 60 km/h\n Time = Distance ÷ Speed = 300 ÷ 60 = 5 hours", "- Second segment:\n Distance = 200 km, Speed = 80 km/h\n Time = 200 ÷ 80 = 2.5 hours", "#### Step 2: Total Distance and Total Time", "- Total Distance = 300 km + 200 km = 500 km\n- Total Time = 5 hours + 2.5 hours = 7.5 hours", "#### Step 3: Compute Average Speed", "Average Speed = Total Distance ÷ Total Time\n= 500 km ÷ 7.5 hours ≈ 66.67 km/h", "---", "### 📊 Why Average Speed Isn’t Just (60 + 80) ÷ 2", "A common mistake is averaging the speeds directly:\n(60 + 80) ÷ 2 = 70 km/h — but this ignores the time spent at each speed. Since the train spends more time at the lower speed (300 km at 60 km/h vs. 200 km at 80 km/h), the actual average speed is lower than a simple arithmetic mean.", "---", "### ✅ Final Answer:\nThe average speed for the entire trip is approximately 66.67 km/h.", "---", "### 💡 Why This Matters", "Understanding average speed helps in:\n- Optimizing train schedules\n- Estimating travel times accurately\n- Comparing different routes or speeds\n- Planning efficient logistics and commuting", "Whether commuting by train or planning freight logistics, knowing how to compute average speed ensures better decision-making.", "---", "### 🔍 Search Intent Recap", "People searching for:\n"What is the average speed for a 300 km train journey at 60 km/h and then 200 km at 80 km/h?"", "want a clear, accurate breakdown using real numbers and step-by-step logic — exactly the explanation provided above.", "---", "### 📌 Key Takeaways:", "- Average speed accounts for both distance and time.\n- Faster travel over shorter distances lowers average speed.\n- Use time = distance ÷ speed for precise calculations.\n- Avoid assuming a simple arithmetic average — real-world speed depends on duration.", "---", "Need to calculate average speeds for rail, road, or flight travel?
