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 determine how many hours will pass before Aaron and Zhang meet, let's analyze their movements: 1. **Initial Distance**: - Aaron is 10 miles away from the store. - Zhang starts at the store. - **Distance between them initially**: 10 miles. 2. **Speeds**: - **Aaron's speed**: 3 miles per hour (toward the store). - **Zhang's speed**: 2 miles per hour (toward Aaron). 3. **Relative Speed**: - Since they are moving towards each other, their speeds add up. - **Combined speed**: 3 mi/h + 2 mi/h = 5 mi/h. 4. **Time to Meet**: - Time = Distance ÷ Speed. - **Time = 10 miles ÷ 5 mi/h = 2 hours**. **Answer:** C. 2 h
