Newton's Law of Cooling states that the rate at which an object cools is proportional to the difference in temperature between the object and the surrounding medium. Thus, if an object is taken from an oven at 303 F and left to cool in a room at 74 F, it's temperature T after t hours will satisfy the differential equation dT/dt = k(t-74)

If the temperature fell to 206 F in 0.7 hours, what will it be in 5 hours?
