Answer:
Step-by-step explanation:
To determine the temperature at 6 pm, let's start by noting the temperature at 9 am, which was -14.4°F. We'll then calculate the temperature changes throughout the day.
Between 9 am and noon, the temperature rose by 11.1°F. So, the temperature at noon would be -14.4°F + 11.1°F = -3.3°F.
Between noon and 3 pm, the temperature decreased by 16°F. Therefore, the temperature at 3 pm would be -3.3°F - 16°F = -19.3°F.
Finally, between 3 pm and 6 pm, the temperature decreased by 19.8°F. Thus, the temperature at 6 pm would be -19.3°F - 19.8°F = -39.1°F.
Please note that these calculations assume a linear temperature change throughout the day, which may not always be the case in reality.
