The Fahrenheit temperature, F(t) of a heated object at time t, in minutes, can be modeled by the function below. Fs is the surrounding temperature, F, is the initial temperature of the object, and k is a constant. F(t) = Fs + (Fo-Fs)e -* Coffee at a temperature of 195' F is poured into a container. The room temperature is kept at a constant 68°F, and k = .05. Coffee is safe to drink when its temperature is, at most, 120°F to the nearest minute , how long will it take until the coffee is safe to drink?
