A 95*C cup of coffee is in a 20*C room. Suppose it is known that the coffee cools at a rate of 1*C per minute when its temperature is 70*C.

What does the differential equation become in this case?

there's sub questions but i cant seem to get the main part needed to answer the others

thanks for any help
 
Do you know Newton's law of cooling:

dT/dt = k * (T - To)

where

To = Ambient (room) temperature
