Alcohol consumption slows people's reaction times. In a controlled government test, it takes a certain driver 1 = 0.29 s to hit the brakes in a crisis when unimpaired and f2 = 1.07 s when drunk. If the car is initially traveling at v = 85 km/h, what additional distance Ax does the car travel before the brakes are applied Ax = m when the person is drunk than it travels when the person is sober
