the temperature is dropping throughout a day as a cold front comes in. in city a the temperature is changing by -5 f per hour, 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
To find out which city is warmer after 5 hours and the difference in their temperatures, we need to calculate the final temperature of each city.
In City A, the temperature is dropping by -5°F per hour for 5 hours.
So, the final temperature in City A is: 70°F - (5°F/hr * 5 hrs) = 70°F - 25°F = 45°F.
In City B, the temperature is dropping by -3°F per hour for 5 hours.
So, the final temperature in City B is: 70°F - (3°F/hr * 5 hrs) = 70°F - 15°F = 55°F.
Therefore, City B is warmer after 5 hours.
The difference in their temperatures is: 55°F - 45°F = 10°F.
