We know that alcohol consumption slows people's reaction times. Suppose that for a particular person, it normally takes 0.37 s to hit the brakes after seeing danger. It takes the same person 1.42 s when drunk. If their car is initially traveling at 84 km/h, how much farther (in meters) does the car travel before the brakes are applied when the person is drunk compared to sober? (Notice that the car's speed is given in km/h but the times given are in seconds and your answer should be in meters, so you'll have to do some unit conversion.)

Question
We know that alcohol consumption slows people's reaction times. Suppose that for a particular person, it normally takes 0.37 s to hit the brakes after seeing danger. It takes the same person 1.42 s when drunk. If their car is initially traveling at 84 km/h, how much farther (in meters) does the car travel before the brakes are applied when the person is drunk compared to sober?
(Notice that the car's speed is given in km/h but the times given are in seconds and your answer should be in meters, so you'll have to do some unit conversion.)
