Question:** A car travels 150 km in 2 hours and then 200 km in 3 hours. What is the average speed for the entire journey?
["Average Speed Calculator: What’s the Average Speed for This 350 km Trip?", "When planning a road trip, one of the most common questions drivers ask is: What is the average speed for the entire journey? Understanding average speed helps you estimate travel times, plan fuel stops, and make better decisions on the road. In this article, we’ll explore how to calculate the average speed for a journey with multiple stages — just like driving 150 km in 2 hours and then 200 km in 3 hours.", "---", "### What Is Average Speed?", "Average speed is defined as the total distance traveled divided by the total time taken for the entire trip. Unlike average velocity, which factors in direction, average speed is a simple reflector of how efficiently you covered distance. It is expressed in kilometers per hour (km/h) or miles per hour (mph).", "---", "### Step-by-Step: Calculating Average Speed for This Journey", "Let’s break down the given journey:", "- First leg:\n Distance = 150 km\n Time = 2 hours", "- Second leg:\n Distance = 200 km\n Time = 3 hours", "#### Step 1: Calculate total distance\nAdd the two distances:\n[\n150\ \ ext{km} + 200\ \ ext{km} = 350\ \ ext{km}\n]", "#### Step 2: Calculate total time\nAdd the two time durations:\n[\n2\ \ ext{hours} + 3\ \ ext{hours} = 5\ \ ext{hours}\n]", "#### Step 3: Apply the average speed formula\n[\n\ ext{Average Speed} = \frac{\ ext{Total Distance}}{\ ext{Total Time}} = \frac{350\ \ ext{km}}{5\ \ ext{hours}} = 70\ \ ext{km/h}\n]", "---", "### The Final Answer: 70 km/h", "With a total distance of 350 km over 5 hours, the car’s average speed for the entire journey is 70 kilometers per hour. This means, on average, the vehicle moved at 70 km/h — a typical speed for highway driving, depending on road conditions and traffic.", "---", "### Why Average Speed Matters", "Knowing your average speed helps in:", "- Planning your trip duration more accurately\n- Managing fuel consumption and battery life (for electric vehicles)\n- Evaluating travel efficiency", "---", "### Summary", "- Total distance: 350 km\n- Total time: 5 hours\n- Average speed: ( \frac{350}{5} = 70\ \ ext{km/h} )\n- Use this formula for any multi-leg journey: average speed = total distance ÷ total time", "Track your trips smarter — and remember: 70 km/h is not just a number, it’s a key to better travel planning!", "---", "Keywords: average speed calculator, average speed formula, road trip average speed, how to calculate average speed, car journey average speed, 150 km in 2 hours 200 km in 3 hours average speed, speed calculation", "Meta Description:\nDiscover how to calculate average speed for a car journey like 150 km in 2 hours then 200 km in 3 hours.
