You are driving a car away from home. Your velocity (miles per hour) t hours after noon is given by v(t) = - 5t* + 44t° - 144t + 170t. At noon you were 150 miles from home. Between 12:00pm and 2:30pm you drove miles. (Round answer to nearest tenth.) A forest fire is found at midnight. It covers 1100 acres then. It is spreading at a rate of f(t) = 4Vt acres per hour. Over the next 21 hours the fire will spread over acres. (Round to nearest tenth.)
