The temperature in City A is decreasing by 5°F per hour, so after 5 hours, the temperature will be 70°F - (5°F/hour * 5 hours) = 70°F - 25°F = 45°F.
The temperature in City B is decreasing by 3°F per hour, so after 5 hours, the temperature will be 70°F - (3°F/hour * 5 hours) = 70°F - 15°F = 55°F.
Therefore, City B is warmer by 10°F (55°F - 45°F). The correct option is City B is warmer by 10°F.
The temperature is dropping throughout the day as a cold front comes in. In city A, the temperature by -5*F per hour, and in City B the temperature is changing by -3*F per hour. If the temperature in both cities started at 70*F, which city is warmer, and what is the difference in their temperatures after 5 hours?
Options:
City B is warmer by 10*F.
City A is warmer by 2*F
City A is warmer by 10 F
City B is warmer by 2*F
