After taking the cooked pie out of the oven in a kitchen that is 70 degrees, you need to allow it to cool (so you won't burn your tongue) before you can eat it. The graph of the temperature of the pie, as well as a few points on the graph of the temperatures at certain times, t, in minutes, is shown below.
