Find two different temperatures whose Celcius and Fahrenheit values are reverses of each other (when rounded to the nearest degree). For example 12 and 21 are reverses of each other.
Help
Hint
32 degrees Fahrenheit is 0 degrees Celcius, and 212 degrees Fahrenheit is 100 degrees Celcius.
Solution
The formula for converting from Fahrenheit to Celcius is: C = 5/9*(F-32). You can use an Excel spreadsheet to calculuate from 32 to 99 degrees Fahrenheit. From the spreadsheet, you'll find that 61 degrees Fahrenheit is 16 degrees Celcius, and 82 degrees Fahrenheit is 28 degrees Celcius.
