A cup of hot coffee initially at 95°C cools to 80°C in 6 min while sitting in a room of temperature 21°C. By Newton's law of cooling, the temperature of the hot coffee- is T(t) = M - Ce-Kt. Determine the value of G and K

The air in a room 15 ft by 12 ft by 12 ft is 3% carbon monoxide. Starting at t=0, fresh air containing no carbon monoxide is blown into the room at a rate of 300 ft/min. If air in the room flows out through a vent at the same rate, when will the air in the room be 0.01% carbon monoxide? The air in the room will be 0.01% carbon monoxide after (Round to two decimal places as needed.) minutes.

The stopping distance d (in feet) for a car traveling v mph when the driver has a reaction time of t is given by d = 1.5tv + 0.06v². A car is traveling 70 mph. If the driver's reaction time is 0.5 sec, what is the stopping distance? ft
