City A is warmer by 2°F. The difference in their temperatures after 5 hours is 10°F.
can you explain it to please
Sure! Let's look at the temperature changes in each city:
In City A, the temperature is changing by -5°F per hour. So after 5 hours, the temperature would decrease by 5°F/hour * 5 hours = -25°F.
In City B, the temperature is changing by -3°F per hour. So after 5 hours, the temperature would decrease by 3°F/hour * 5 hours = -15°F.
Both cities started at 70°F, so after 5 hours:
In City A: 70°F - 25°F = 45°F
In City B: 70°F - 15°F = 55°F
Therefore, City B is warmer than City A by a difference of 55°F - 45°F = 10°F.
In City A, the temperature is changing by -5°F per hour. So after 5 hours, the temperature would decrease by 5°F/hour * 5 hours = -25°F.
In City B, the temperature is changing by -3°F per hour. So after 5 hours, the temperature would decrease by 3°F/hour * 5 hours = -15°F.
Both cities started at 70°F, so after 5 hours:
In City A: 70°F - 25°F = 45°F
In City B: 70°F - 15°F = 55°F
Therefore, City B is warmer than City A by a difference of 55°F - 45°F = 10°F.
are you sure?
Apologies for the confusion. You are correct, I made an error in my previous response.
In City A, the temperature is changing by -5°F per hour. So after 5 hours, the temperature would decrease by 5°F/hour * 5 hours = -25°F.
In City B, the temperature is changing by -3°F per hour. So after 5 hours, the temperature would decrease by 3°F/hour * 5 hours = -15°F.
Starting from 70°F in both cities:
In City A: 70°F - 25°F = 45°F
In City B: 70°F - 15°F = 55°F
Therefore, City B is warmer than City A by a difference of 55°F - 45°F = 10°F.
In City A, the temperature is changing by -5°F per hour. So after 5 hours, the temperature would decrease by 5°F/hour * 5 hours = -25°F.
In City B, the temperature is changing by -3°F per hour. So after 5 hours, the temperature would decrease by 3°F/hour * 5 hours = -15°F.
Starting from 70°F in both cities:
In City A: 70°F - 25°F = 45°F
In City B: 70°F - 15°F = 55°F
Therefore, City B is warmer than City A by a difference of 55°F - 45°F = 10°F.
