4. According to Newton’s law of cooling, the rate at which a body cools is proportional to the difference between the temperature of the body and that of the surrounding medium. Let 0 represent the temperature (in °C) of a body in a room whose temperature is kept at a constant 18°. If the body cools from 70° to 57° in 5 minutes, how much longer will it take for its temperature to drops to 40°?
