2. According to Newton's cooling law, the rate of cooling of a hot body is pro- portional to the difference between the temperatures of the hot body and the environment. If the room temperature is 30° Celsius and the temperature of a hot body in the room cools down to 50° from 100° Celsius in just 5 minutes, then how many more minutes will it take to cool down to 40°?
