**How Far Will a Car Travel at Constant Speed? A Clear Look at Distance, Time, and Real-World Applications** Ever wonder how far a vehicle travels when moving steadily, like on a long highway route? A simple question like this — *If a car covers 120 kilometers in 1.5 hours at a constant speed, how far will it go in 3.5 hours?* — connects to everyday journey planning, fuel efficiency research, and transportation trends. The answer reveals not just math, but also patterns in movement across cities and states. This scenario reflects a fundamental principle of physics and real-world driving: when speed remains constant, distance increases proportionally with time. The number 120 km in 1.5 hours defines a reliable pace, making it easy to forecast travel outcomes—vital for anyone relying on accurate estimations, whether navigating daily commutes or planning road trips. ### The Science Behind Constant Speed Travel
