A car travels 120 miles in 2 hours at a constant speed. It then continues to travel for another 3 hours at a speed that is 10 mph faster than its initial speed. What is the total distance covered by the car?

**Why Are Users Exploring How Speeds and Time Shape Long Trips?**
Travel math puzzles like this—where a car moves steadily, then speeds up—are more than just numbers on paper. With rising fuel costs, evolving commuting habits, and increased interest in efficient travel planning, many US drivers are curious about realistic journey calculations. Recent searches for fuel efficiency tips, route planning, and real-world driving dynamics have fueled attention around scenarios like driving 120 miles at constant speed, then accelerating. Understanding total distance helps travelers estimate fuel needs, time costs, and route planning—key priorities in today’s mobile-first, time-conscious travel culture. **The Mechanics Behind the Trip: Breaking Down Speed, Time, and Distance**
Let’s explore what happens when a car travels 120 miles at a steady speed, then continues for 3 hours at 10 mph faster. The core principle is distance = speed × time—but such scenarios reveal the trade-offs between consistency and increased velocity. Assuming constant speed for the first 120-mile stretch at 60 mph, that opens the door to a calculated speed boost. At 70 mph for the next 3 hours, the car covers 210 miles. Together, the full journey spans 330 miles—a figure that matters for planning long-distance outings, budgeting fuel, or understanding travel efficiency. **Why This Equation Matters Beyond the Numbers**
People are drawn to such problems not just for education—but for real-world utility. Whether calculating road trip duration during weekend getaways, optimizing delivery routes, or comparing hybrid efficiency, this model applies to daily driving decisions. The math also reflects broader trends in transportation: variable speeds due to traffic, highways, and fuel economy priorities. Users seeking clarity here aren’t just testing knowledge—they’re building practical insight that supports smarter, more informed choices on the go. **Answer: The Total Distance Covers All Ground**
At the core, the total distance equals 330 miles.
