An oven is preheated and then remains at a constant temperature. A potato is placed in the oven to bake. Suppose that the temperature T in ° F of the potato t minutes later is given by T = 400 − 325 0.97 t . The potato will be considered done when its temperature is anywhere between 260 ° F and 280 ° F . (a) During what interval of time would the potato be considered done? (b) How long does it take for the difference between the potato and oven temperatures to be cut in half?
