Final answer:
The temperature in Silver City, which is four degrees less than Franklin City's -11°C, is -15°C. Additionally, a 40.0°F decrease in temperature is equivalent to a 22.22°C decrease.
Step-by-step explanation:
The temperature in Franklin City is -11°C, and the temperature in Silver City is four degrees less, so to find out the temperature in Silver City, you would subtract four degrees from the temperature in Franklin City. The calculation is as follows:
- Franklin City's temperature: -11°C
- Silver City's temperature is four degrees less: -11°C - 4°C = -15°C
Therefore, the temperature in Silver City is -15°C.
To address the reference information provided: When the temperature decreases by 40.0°F, it decreases by 40.0°F × 5/9 = 22.22°C (approximately) since the ratio of Fahrenheit to Celsius is 9/5.
