# Differential equations: Newton's Law of Coolin

Need help on this..DE Newton's Law of Cooling

A thermometer is removed from a room whose ambient temperature is 70° F and is taken outside.

After one minute the thermometer reads 60° F and after three minutes, it reads 55° F. **What is the outside
temperature (which is assumed to be constant)**? Find your answer by solving DE model of Newton’s Law

of cooling.
