An object was left in a room of unknown surrounding temperature. The temperature. f the object was summarized below with respect to the time f (in minutes) the object was initially observed. • When t-0, the temperature of the object is 23 degrees Celsius. • When t-10 minutes, the temperature of the object is 27 degrees Celsius. • When t - 20 minutes, the temperature of the object is 30.2 degrees Celsius. In minutes, when will the object have the temperature 40 degrees Celsius? Assume the system obeys Newton's Law of Cooling and the surrounding temperature of the room did not change. Put your answer accurate to four decimal places. No need to put in the units of measurement.
