To find the temperature at 17:00, we need to determine how many hours have passed since midday (12:00) and then calculate the decrease in temperature over that time.
From midday to 17:00, 5 hours have passed.
Given that the temperature decreases by 2°C per hour, we can calculate the total decrease in temperature:
Total decrease = 2°C/hour * 5 hours = 10°C
Starting from 1°C at midday, if the temperature decreases by 10°C, the temperature at 17:00 would be:
1°C - 10°C = -9°C
So, the temperature at 17:00 would be -9°C.
