Distance equals rate times time. For the first segment: 60 mph×2 h=120 miles60 \text{ mph} \times 2 \text{ h} = 120 \text{ miles}. For the second: 45 mph×3 h=135 miles45 \text{ mph} \times 3 \text{ h} = 135 \text{ miles}. Total distance =120+135=255= 120 + 135 = 255. Choose C. This problem aligns with CLI’s Mathematical (Logical) Reasoning outcomes by requiring students to parse a multi-stage scenario, identify the relevant relation d=rtd = rt, compute each segment, and aggregate. A common pitfall is averaging speeds ((60+45)/2(60+45)/2) then multiplying by total time—this is invalid unless times (or distances) are equal in the right way. Here, times differ, so compute per segment. These rate problems build competency for more advanced proportional reasoning (e.g., weighted means, piecewise rates, or variable-speed travel). They also encourage unit mindfulness—hours with mph yield miles—reinforcing dimensional analysis, another CLI reasoning expectation.
