Solve the Problem $25^{\circ}$ And the Body Cools From $110^{\circ}$ To $65^{\circ}$ In 30 Minutes, Find the Temperature of the Body After

Solve the problem.
-Newton's law of cooling states that the rate at which a body changes temperature is proportional to the difference between its temperature and that of the surrounding medium. If a body is in air of temperature $25^{\circ}$ and the body cools from $110^{\circ}$ to $65^{\circ}$ in 30 minutes, find the temperature of the body after 60 minutes. (Round to nearest degree.)

A) $47^{\circ}$
B) $39^{\circ}$
C) $44^{\circ}$
D) $40^{\circ}$
