Alcohol consumption slows people's reaction times. In a controlled government test, it takes a certain driver 0.320 s to hit the brakes in a crisis when unimpaired and 1.00 s when drunk. The car is initially traveling at 110.0 km/h. 1) How much farther does the car travel before coming to a stop when the person is drunk compared to sober

Answer:


\triangle d=21.726m

Step-by-step explanation:

From the question we are told that:

Unimpaired time to hit break
t_i=0.320s

Drunk time
t=1s

Initial Velocity
v=110km/h

Generally the equation for Average velocity is mathematically given by


V_(avg)=(\triangle d)/(\triangle t)

Therefore


\triangle d=v.dt


\triangle d=31.95*(1-0.32)


\triangle d=21.726m
