Answer:
3*C
Explanation:
We can Frame an equation, taking the previous temperature as "x" and adding 2 by every hour.
Previous Temprature + 2 = New Temprature
Therefore by this equation:
at 8AM , the Temperature is -5 + 2 = -3*c
at 9AM , the Temperature is -3 + 2 = -1*c
at 10 AM, the Temperature is -1 + 2 = 1*c
Therefore at 11AM , the Temperature will be 1 + 2 = 3*c
Hope it helps.
