A road perpendicular to a highway leads to a farmhouse located a = 1.2 km away. An automobile travels past the farmhouse at a speed of v = 84 km/h. How fast is the distance between the automobile and the farmhouse increasing when the automobile is 3.6 km past the intersection of the highway and the road? Let / denote the distance between the automobile and the farmhouse, and let s denote the distance past the intersection of the highway and the road. a v km/h Automobile (Use decimal notation. Give your answer to three decimal places.)
