In City A, the temperature is changing by -5°F per hour, so after 5 hours, the temperature in City A would be 70°F + (-5°F/hour * 5 hours) = 70°F - 25°F = 45°F.
In City B, the temperature is changing by -3°F per hour, so after 5 hours, the temperature in City B would be 70°F + (-3°F/hour * 5 hours) = 70°F - 15°F = 55°F.
Therefore, City B is warmer by 55°F - 45°F = 10°F.
The temperature is dropping throughout the day as a cold front comes in. In City A, the temperature is changing by −5°F per hour, and in City B the temperature is changing by −3°F per hour. If the temperatures in both cities started at 70°F , which city is warmer, and what is the difference in their temperatures after 5 hours?
