. Cooling an Engine Suppose you're driving your car on a cold winter day (20°F outside) and the engine overheats (at about 220°F). When you park, the engine begins to cool down. The temperature T of the engine t minutes after you park satisfies the equation т- 20° In = -0.11t 200 (a) Solve the equation for T. (b) Use part (a) to find the temperature of the engine after 20 min (t = 20).
