43°F. 50°F. 73°F. 90°F.
I gave my students this multiple choice question: A glass of water at 110°F is placed in a room next to a glass of water that is 50°F. The temperature of the room is 73°F at all times. If the two glasses were left in the room overnight, the temperature for both glasses of water the next day would be approximately

Only one answer is correct among these 4 choices:
- 43°F.
- 50°F.
- 73°F.
- 90°F.

Could you tell me which one is correct?

73°F.
