Kara knows that the speed of the 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 14Vd, where d is the length of the skid mark (in meters) and s is,the speed of the car (in km/h), before the brake pedal is of the function is given by s = pushed. If she had to brake suddenly for a red light and left skid marks that were 25 m long, at what speed was she traveling before she had to brake? O 1.33 km/h O 3.189 km/h O 44.643 km/h O 70 km/h
