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, 34ftthis 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.

Looks right to me.
