Final answer:
The temperature dropped 5°C every hour for 7 hours, which resulted in a total drop of 35°C when calculated as 5°C × 7 hours.
Step-by-step explanation:
The student's question is about calculating the total temperature change when it drops consistently over some time. In this case, the temperature drops by 5°C every hour for 7 hours. To find the total change, we multiply the hourly drop in temperature by the total number of hours, which is 5°C × 7 hours = 35°C. Therefore, the correct answer is A. 35°C. To find the total number of degrees the temperature changed, we can multiply the rate of change (5°C/hour) by the number of hours (7 hours). So, the total temperature change is 5°C/hour × 7 hours = 35°C.
