We know that the temperature at 8:00 AM was 5°C, and it increased by 2°C every hour until 12:00 PM.
To find the temperature at 11:30 AM, we need to calculate the number of hours between 8:00 AM and 11:30 AM.
From 8:00 AM to 9:00 AM, the temperature increased by 2°C.
From 9:00 AM to 10:00 AM, the temperature increased by another 2°C.
From 10:00 AM to 11:00 AM, the temperature increased by another 2°C.
From 11:00 AM to 11:30 AM, half an hour has passed, so the temperature would increase by half of the regular hourly increase.
Therefore, the temperature at 11:30 AM would be 5°C + 2°C + 2°C + 2°C + (2°C / 2) = 5°C + 8°C + 1°C = 14°C.
So, the temperature at 11:30 AM would be 14°C in Austria.
