A car travels 120 kilometers at an average speed of 60 km/h, then another 180 kilometers at an average speed of 90 km/h. Calculate the total time taken for the trip.

["Title: Total Trip Time Calculation: A Journey Explained", "When planning long-distance travel, understanding how varying speeds affect total journey duration is essential. Consider the following scenario: a car travels 120 kilometers at an average speed of 60 km/h, followed by 180 kilometers at 90 km/h. In this SEO-optimized article, we break down the trip step by step and calculate the total time taken.", "---", "### Understanding Average Speed and Time", "Average speed is calculated as total distance divided by total time. However, for road trips, breaking the journey by segments makes it easier to compute total travel time, especially when speeds differ.", "---", "### Segment 1: 120 km at 60 km/h", "Use the formula:", "[\n\ ext{Time} = \frac{\ ext{Distance}}{\ ext{Speed}}\n]", "[\n\ ext{Time}_1 = \frac{120 \ ext{ km}}{60 \ ext{ km/h}} = 2 \ ext{ hours}\n]", "---", "### Segment 2: 180 km at 90 km/h", "[\n\ ext{Time}_2 = \frac{180 \ ext{ km}}{90 \ ext{ km/h}} = 2 \ ext{ hours}\n]", "---", "### Total Trip Time", "Add both segments:", "[\n\ ext{Total Time} = 2 \ ext{ hours} + 2 \ ext{ hours} = \mathbf{4 hours}\n]", "---", "### Real-World Application & SEO Insights", "Understanding trip duration helps in travel planning, scheduling, and fuel efficiency analysis—key factors for both drivers and content targeting search terms like “total travel time,” “average speed vs time,” and “distance speed calculation.” Optimizing for keywords such as “how long is a 120km to 180km trip at different speeds?” boosts visibility for users searching for accurate journey estimates.", "---", "### Summary", "- First leg: 120 km at 60 km/h = 2 hours\n- Second leg: 180 km at 90 km/h = 2 hours\n- Total trip time: 4 hours", "By calculating segment-by-segment, we ensure precise timing and clarity—critical for informed travel decisions.
