A cup of tea is prepared in a preheated cup with hot water so that the temperature of both the cup and the brewing tea is initially 190 degree Fahrenheit. The cup is then left to cool in a room kept at a constant 72 degree Fahrenheit. Two minutes later, the temperature of the tea is 150 degree Fahrenheit. Determine the time required for the tea to reach 100 degree Fahrenheit.
