A car travels 150 miles in 3 hours. Calculate its average speed in miles per hour. With rising interest in travel efficiency and fuel performance, many American drivers and buyers are calculating average speeds for real-world decisions—whether planning a road trip, evaluating vehicle capabilities, or comparing market data. This query reflects a growing curiosity about how distance and time shape practical mobility. The average speed is determined by dividing total distance by total time. For a car covering 150 miles in 3 hours, the calculation is simple: 150 divided by 3 equals 50. The result is 50 miles per hour—meaning the vehicle travels at an average speed of 50 mph over the journey. This figure represents a steady pace, reflecting typical highway or commuter conditions without net stops. In the U.S., understanding average speed is more than a math exercise—it helps drivers estimate fuel needs, assess travel time, and navigate logistics efficiently. For example, a 150-mile route at around 50 mph requires roughly two hours and fifteen minutes, a benchmark often used in planning weekend getaways or regional deliveries.
