Newton's law of cooling states that the temperature of an object
changes at a rate proportional to the difference between its
temperature and that of its surroundings. Suppose that the
temperature of a cup of coffee obeys Newton's law of cooling. If
the coffee has a temperature of 205 degrees Fahrenheit when freshly
poured, and 1 minutes later has cooled to 190 degrees in a room at
64 degrees, determine when the coffee reaches a temperature of 150
degrees.
The coffee will reach a temperature of 150 degrees in how many
minutes?
