A car travels 150 kilometers at an average speed of 75 km/h, then continues another 200 kilometers at 100 km/h. What is the total time spent traveling?
["Total Travel Time Breakdown: 150 km at 75 km/h and 200 km at 100 km/h", "Understanding travel time is essential for effective planning, whether you're commuting, road-tripping, or analyzing transportation efficiency. In this article, we break down the total time spent on a journey consisting of two distinct segments: initially driving 150 kilometers at an average speed of 75 km/h, then continuing for 200 kilometers at 100 km/h.", "### Step 1: Calculate Time for the First Segment", "In the first part, a car travels 150 kilometers at an average speed of 75 km/h. To find the travel time, use the formula:", "[\n\ ext{Time} = \frac{\ ext{Distance}}{\ ext{Speed}}\n]", "[\n\ ext{Time}_1 = \frac{150\ \ ext{km}}{75\ \ ext{km/h}} = 2\ \ ext{hours}\n]", "This initial leg of the journey takes exactly 2 hours.", "### Step 2: Calculate Time for the Second Segment", "The second segment covers 200 kilometers at 100 km/h. Applying the same formula:", "[\n\ ext{Time}_2 = \frac{200\ \ ext{km}}{100\ \ ext{km/h}} = 2\ \ ext{hours}\n]", "This second leg takes 2 hours as well.", "### Step 3: Compute Total Travel Time", "Add the times from both segments:", "[\n\ ext{Total Time} = \ ext{Time}_1 + \ ext{Time}_2 = 2\ \ ext{hours} + 2\ \ ext{hours} = 4\ \ ext{hours}\n]", "### Conclusion", "The entire journey—spanning 150 km at 75 km/h followed by 200 km at 100 km/h—takes a total of 4 hours—an optimal balance between speed and distance. This calculation highlights how varying speeds along a route directly impact total travel time, making it valuable knowledge for travelers and logistics planners alike.", "Whether you're estimating commute times or analyzing vehicle efficiency, knowing how distance and speed combine to affect duration is key. For a simple 350-kilometer trip composed of two different leg speeds, understanding these time calculations ensures more accurate planning and smoother journeys.", "---", "Keywords: car travel time, average speed calculation, total driving time, 150 km at 75 km/h, 200 km at 100 km/h, time and distance formula, road trip planning, transportation efficiency."]
