A self-driving car and one driven by a person are both initially traveling at 60 mi/h along a straight road. Suddenly, a cow wanders onto the road ahead. The person sees the cow and steps on the brakes after 0.25 seconds, while the robotic system in the self-driving care "sees" the cow and starts braking after 0.50 seconds. How much further has the self-driving car traveled before it starts braking? (5280 ft = 1 mi). A. 15 ft B. 20 ft C. 22 ft D. 31 ft
