The temperature T of a cup of coffee is a function T(t) where t is the time in minutes. The room temperature is http://homework.math.ucsb.edu/webwor...7d6c166211.png Celsius. The rate at which the coffee cools down is proportional to the difference between the temperature of the coffee and the room temperature. Use this information to write a differential equation describing the derivative of the coffee temperature in terms of T and t. Use C as your proportionality constant. C should be a positive number. Write T instead of T(t).

Help! Thanks :) I'm just having a hard time deciphering what the questions wants me to write in terms of a formula, and I'm sure I can go from there.
