A road perpendicular to a highway leads to a farmhouse located a = 1.5 km away. An automobile travels past the farmhouse at a speed of v = 85 km/h. How fast is the distance between the automobile and the farmhouse increasing when the automobile is 3.7 km past the intersection of the highway and the road? Let I denote the distance between the automobile and the farmhouse, and let s denote the distance past the intersection of the highway and the road. speed of I at given s-value: (Use decimal notation. Give your answer to three decimal places.) v km/h Automobile 78.786 Incorrect km/h
