Answer:
The temperature at 11:30 will be 2°C
Explanation:
The number of hours between 8:00 and 11:30 is 3.5 hrs
Therefore, if the temperature increases by 2°C every hour, the total increase of temperature is 2 x 3.5 = 7°C
If the initial temperature was -5°C, then the final temperature will be -5 + 7 = 2°C
So the temperature at 11:30 will be 2°C
