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 -3F per hour if the temperatures in both cities started at 70F which city is warmer and what is the difference in their temperatures after 5 hours? City A is warmly 10F City B is warmer by 2F City B warmer by 10F city A warmer by 2 F
After 5 hours, the temperature in City A would be 70 - (5*5) = 70 - 25 = <<70-(5*5)=45>>45F.
The temperature in City B would be 70 - (3*5) = 70 - 15 = <<70-(3*5)=55>>55F.
Thus, City B is warmer by 55 - 45 = <<55-45=10>>10F.
