Let y represent the temperature (in °C) of an object in a room whose temperature is kept at a constant50°. If the object cools from 110° to 90° in 10 minutes, how much longer will it take for its temperatureto decrease to 80°?A hard-boiled egg at 85°C is put in a pan under running 18°C water to cool. After 5 minutes, the egg'stemperature is found to be 38°C. How much longer will it take the egg to reach 20°C?
