When a cake is removed from an oven its temperature is measured at 300 degree F. Three minutes later its temperature is 200 degree F. How long will it take to cool off to a room temperature of 70 degree F?

  1. assuming a constant rate of cooling, it will take x total minutes, where

    300 - (300-200)/3 x = 70
    x = 6.9

    So, in 3.9 more minutes it will have cooled to 70°F
