Xr13-53 How effective is an antilock braking system

(ABS), which pumps very rapidly rather than lock and thus avoid skids? As a test, a car buyer organized an experiment. He hit the brakes and, using a stopwatch, recorded the number of seconds it took to stop an ABS-equipped car and another identical car without ABS. The speeds when the brakes were applied and the number of seconds each took to stop on dry pavement are listed here. Can we infer that ABS is better?

Speeds 20 25 30 35 40 45 50 55 ABS 3.6 4.1 4.8 5.3 5.9 6.3 6.7 7.0 Non-ABS 3.4 4.0 5.1 5.5 6.4 6.5 6.9 7.3
