Beginning drivers soon learn that bringing an automobile to a stop requires greater distances for higher speeds. A formula that approximates the stopping distance under normal driving conditions is
d = 1.1v + 0.055v2
where v = speed of the auto in miles per hour and d = distance in feet required to bring the auto to a stop.
(a) Find the stopping distance of an auto traveling 15 mph. (Round your answer to the nearest foot.)
ft
(b) Find the stopping distance of an auto traveling 30 mph. (Round your answer to the nearest foot.)
