C. realize. MI72/3 Topic 4 Test (LMS graded) Aaron starts walking at a rate of 3 mi/h on a road toward a store 10 mi away. Zhang leaves the store when Aaron starts walking, and he walks toward Aaron along the same road at 2 mi/h. How many hours will pass before they meet? A. 1.5 h B. 10 h C. 2 h D. 3 h

To find out how long it will take for Aaron and Zhang to meet, we can set up an equation based on their rates of speed and the distance between them. Aaron walks at 3 miles per hour (mi/h) and Zhang walks at 2 mi/h. Together, they are closing the distance between them at a combined speed of 3 + 2 = 5 mi/h. Since the store is 10 miles away from Aaron's starting point, we can use the equation: Time = Distance / Speed Time = 10 miles / 5 mi/h = 2 hours. So, the answer is C. 2 h.
