The temperature is dropping throughout the day as a cold front in in city a the temperature is changing by -5 per hour and the city b the temperature is changing by -3 per hour if the temperatures in both cities started at 70 grades Fahrenheit which cit is warmer and what is the difference in their temperatures after 5 haour
After 5 hours, the temperature in City A will have dropped by a total of -5 * 5 = -25 degrees Fahrenheit.
Similarly, the temperature in City B will have dropped by a total of -3 * 5 = -15 degrees Fahrenheit.
The final temperature in City A will be 70 - 25 = 45 degrees Fahrenheit.
The final temperature in City B will be 70 - 15 = 55 degrees Fahrenheit.
Therefore, City B is warmer than City A by 55 - 45 = 10 degrees Fahrenheit.
