Speed (km/h) 40 60 80 90 100 Stopping Distance (m) 6.6 14.9 26.5 33.5 41.4 Time left 0:31:52 The data can be modelled by the quadratic regression equation in the form y = ax² + bx + C, where x represents the speed and y represents the stopping distance. If the stopping distance of the car is 30.7 m, then the car was travelling at a speed, to the nearest tenth, of km/h.
