The temperature in City A is changing by -5 F per hour for 5 hours, so the total change in temperature in City A is -5 F/hour * 5 hours = -25 F.
The temperature in City B is changing by -3 F per hour for 5 hours, so the total change in temperature in City B is -3 F/hour * 5 hours = -15 F.
Initially, both cities start at 70 F. After 5 hours, the temperature in City A would be 70 F - 25 F = 45 F.
After 5 hours, the temperature in City B would be 70 F - 15 F = 55 F.
The difference in their temperatures after 5 hours is 55 F - 45 F = 10 F.
Therefore, the correct answer is:
A. City B is warmer by 10 F.
The temperature is dropping throughout the day as a cold front comes in City A. The temperature is changing by -5 F per hour and in City B the temperature is changing by -3 F 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
A. City B is warmer by 10 F
B. City A is warmer by 10 F
C. City B is warmer by 2 F
