At 1:00 PM, a thermometer reading 80°F is taken outside where the temperature is constant. At 1:05 PM, the thermometer reads 35°F more than the surrounding temperature. Forty minutes after being taken outside, the thermometer reading differs from the outside temperature by 15°F. Determine the outside temperature. How long will it take for the same thermometer to cool from 100 °F to 60°F in air, which is maintained at 50°F?
