Asked by Jordan
On a cold winter night, Anna makes a cup of hot cocoa. When she takes the
first sip, she realizes that the cocoa is too hot to drink. She drops a thermometer into the
cup and discovers that the cocoa is 170° F. After 20 minutes, she tries again and the
cocoa is still too hot at 130°F. She assumes the cocoa will be ready to drink when it is
110°F. If the room temperature is 70° F, how long will it take for the cocoa to cool from
170° F to 110° F? Use Newton's Law of Cooling.
