Question
**Problem 8: Temperature Change of an Object in a Room** A 100°F hot object is brought into a room that is at 60°F. Exactly five minutes later, its temperature becomes 90°F. When will its temperature be exactly 15 minutes later? **Explanation:** This problem involves understanding how the temperature of the object changes over time when placed in a room with a different temperature. The object initially at 100°F cools to 90°F in 5 minutes. The task is to determine its temperature 15 minutes after it has been brought into the room. This can be modeled using Newton's Law of Cooling, which describes the rate of change of temperature of an object in relation to its surroundings.
