**A car and a truck start from the same point and travel in opposite directions. The car travels at 65 mph, the truck at 55 mph. After how many hours will they be 540 miles apart?**
This scenario sparks curiosity—two vehicles beginning from the same spot, moving in opposing paths, creating a growing distance over time. In a country where road infrastructure and logistics deeply shape daily life, such a question surfaces in conversations across bins, trucks, and commuters’ phones: how do speed, distance, and direction work together? People are naturally drawn to this kind of problem not just out of math interest, but because it mirrors real-world movement patterns—commuters, freight, and travel paths rarely move in the same direction. With rising costs of fuel, evolving delivery demands, and growing interest in mobility trends, users increasingly seek clear answers to planning travel, shipments, and route logistics. Mathematically, the separation grows linearly based on combined speed. Since the car moves at 65 mph and the truck at 55 mph, their relative speed—how fast the distance between them increases—is 65 + 55 = 120 miles per hour. The gap expands steadily: every hour adds 120 miles to the total separation. To find when the distance reaches 540 miles, divide the target distance by relative speed:
540 miles ÷ 120 mph = 4.5 hours.
