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?(1 point) Responses City B is warmer by 10°F. City B is warmer by 10 degrees F . City B is warmer by 2°F. City B is warmer by 2 degrees F . City A is warmer by 2°F. City A is warmer by 2 degrees F . City A is warmer by 10°F.
The temperature in City A after 5 hours will be 70°F - 5°F/hour * 5 hours = 70°F - 25°F = 45°F.
The temperature in City B after 5 hours will be 70°F - 3°F/hour * 5 hours = 70°F - 15°F = 55°F.
Therefore, City B is warmer by 10°F.
The correct response is City B is warmer by 10 degrees F.
