The temperature is -4° F at 8 A.M. The temperature rises 3° F each hour over the next several hours. Which best represents the temperature at noon?
-4 + 3(12-8) = ?
To find the temperature at noon, we need to determine how many hours have passed since 8 A.M. and then calculate the increase in temperature.
Since there are four hours between 8 A.M. and noon, the temperature would increase by 3° F per hour for four hours.
To calculate this, we can multiply the rate of temperature increase (3° F) by the number of hours (4 hours):
3° F * 4 hours = 12° F
Therefore, the temperature at noon would be 12° F higher than the initial temperature of -4° F.
To find the final temperature, we add the increase in temperature to the initial temperature:
-4° F + 12° F = 8° F
So, the temperature at noon would be 8° F.
