On my way to work, I pass by a digital thermometer outside a bank that
displays the temperature to the nearest integer, alternating
back and forth between Fahrenheit and Celsius at four-second
intervals.
The other day, when I was going to
work, I noticed that the temperatures displayed in
Fahrenheit and Celsius were simply reverse digits of each other.
Well, it warmed up nicely during the day, and
when I was on my way home, I looked at the same
thermometer.
Imagine my shock when, again, the
Fahrenheit and Celsius temperature displays were simply reversed digits of each other!
What was the temperature when I came in
to work, and what was it when I was on my way home?
Note: To convert from degrees Fahrenheit to Celsius, subtract 32 then multiply by 5/9. To convert the other way, simply do the opposite (multiply by 9/5 and add 32). Ignore leading zeroes.
