To find the temperature at 7 p.m., we need to calculate how much the temperature has dropped over the four hours from 3 p.m. to 7 p.m.
The temperature fell steadily by 28°F every hour for 4 hours. So, we can calculate the total drop in temperature:
\[
\text{Total drop} = 28°F \times 4 \text{ hours} = 112°F
\]
Now, we subtract the total drop from the initial temperature at 3 p.m.:
\[
\text{Initial temperature} = 48°F
\]
\[
\text{Temperature at 7 p.m.} = 48°F - 112°F = -64°F
\]
It seems there was a misunderstanding in the options provided. The temperature is actually -64°F, which is not one of the options (8F, 4F, -2F, -4F). Could you please double-check the values or present the question again?
