f.c.f.s.p. (11/25 answer)

95.5 degree Fahrenheit.

If you need a reminder, the question was:
your barista hands you your cup of coffee and it's 140° F. ten minutes later, you remove your thermometer from your pocket protector and measure and it's now 120° F.
assuming exponential decay in temperature (who wouldn't?) and that room temperature is 70°, what will the temperature be in 20 more minutes, 30 minutes from when it was handed to you?
