**Is a car’s speed truly 50 km/h over the entire trip? Understanding average speed from a 150-kilometer to 100-kilometer drive** When a car travels 150 kilometers in exactly 3 hours, then continues another 100 kilometers in 2 hours, a key question emerges: what is the average speed for the full journey? This curiosity isn’t just a math puzzle—it reflects growing interest in personal mobility, fuel efficiency, and travel planning in today’s fast-changing landscape. Many users are seeking clear, trustworthy insights to better understand driving performance, especially as electric vehicles and shared mobility reshape long-distance travel. What drives this conversation? Long-distance trips—whether for commuting, road trips, or business travel—are central to daily life across the United States. With rising fuel costs, increased focus on vehicle efficiency, and growing demand for accurate travel apps, users need precise information to estimate journey time, budget fuel needs, or compare vehicle models. The combination of a 3-hour segment followed by a 2-hour stretch naturally invites a deeper look at how average speed is calculated—not just as a quick figure, but as a meaningful snapshot of driving conditions. To answer the core question: the car’s average speed for the entire journey is determined by total distance divided by total time. The car travels 150 km + 100 km = 250 kilometers over 3 hours + 2 hours = 5 hours. This gives an average speed of 250 km ÷ 5 hr = 50 km/h. While apparent speed varied between 50 km/h and 75 km/h depending on road conditions, terrain, and speed limits, the sustained pace over time results in a steady average.
