It is not possible to answer this question without information about the objects and their respective speeds or velocities.
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 −3°F per hour. 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?(1 point) Responses City A is warmer by 2°F. City A is warmer by 2 degrees F . City B is warmer by 10°F. City B is warmer by 10 degrees F . City B is warmer by 2°F. City B is warmer by 2 degrees F . City A is warmer by 10°F.
After 5 hours, the temperature in City A would decrease by (−5°F/hour) * 5 hours = −25°F, resulting in a temperature of 70°F - 25°F = 45°F.
In City B, the temperature would decrease by (−3°F/hour) * 5 hours = −15°F, resulting in a temperature of 70°F - 15°F = 55°F.
Therefore, City B is warmer by 55°F - 45°F = 10°F.
So, the correct response is: City B is warmer by 10 degrees F.
In City B, the temperature would decrease by (−3°F/hour) * 5 hours = −15°F, resulting in a temperature of 70°F - 15°F = 55°F.
Therefore, City B is warmer by 55°F - 45°F = 10°F.
So, the correct response is: City B is warmer by 10 degrees F.
