A Ann knows that the speed of a car before it brakes suddenly is a function of the length of the skid marks left by its tires on the road and that the equation of the function is given by S 8√d, where d is the length of the skid marks (in meters), and s is the speed of the car (in km/h), before the brake pedal is pushed. If she had to brake suddenly for a stop sign and left skid marks 40 m long, at what speed was she traveling before she had to break? 320 km/h 25 km/h No Solution 50.6 km/h
