Answer:
The temperature at midnight is 100°F.
Explanation:
We are given that early this morning the temperature was 54°F, around noon the temperature increase by 45°, at 5 PM a north wind made the temperature fall by 49°F but just before midnight the wind started to blow for from the south making the temperature in rise by 50°F.
Firstly, the early morning temperature was = 54°F
Now, it is stated that around noon the temperature increase by 45°, so the temperature around noon will be = 54°F + 45°F = 99°F
At 5 PM a north wind made the temperature fall by 49°F, this means there will be a decrease in the temperature level = 99°F - 49°F = 50°F
Finally, just before midnight; there is an increase in the temperature level of 50°F, so the temperature at midnight would be = 50°F + 50°F = 100°F
Hence, the temperature at midnight is 100°F.
