A forest fire is found at midnight. It covers 1100 acres then. It is spreading at a rate of f(t) = 4/t acres per hour. Over the next 22 hours the fire will spread over acres. (Round to nearest tenth.) You are driving a car away from home. Your velocity (miles per hour) t hours after noon is given by v(t) = - 5t* + 41t° - 140t + 180t. At noon you were 155 miles from home. Between 12:00pm and 3:30pm you drove miles. (Round answer to nearest tenth.)
