Drunk driver reaction time increased stopping distance

  1. Sep 25, 2011 #1
    1. The problem statement, all variables and given/known data

    Human reaction times is sometimes worsened by alcohol. How much farther would a drunk driver's car travel before he hits the breaks than a sober drivers car? assume both cars are initially traveling 49 mi/h the sober driver takes .33s to hit the brakes and the drunk driver takes 1s.
    a, 53ft
    b, 48ft
    c, 34ft-this is wrong
    d,58 ft

    2. Relevant equations

    3. The attempt at a solution
    i just tried it again on paper and i think i found .0091194444miles is the difference. so that would be like 14 meters which is 48 feet. is this what you got. i did 49mi/hr/60/60=.0136mi/s*.33= .0044916667 and subtracted that from .0136 which got me .00911 and then just converted.
