Question 919686: car a and the car b are 400 miles apart and headed straight toward each other. car a is going 120 mph, and the car b is going 130 mph. how many hours will it take for the accident to occur? Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! t = D/r, times the same before impact
x the Distance traveled by faster car | Cross Multiplying to solve
120x = 130•400 - 130x
250x = 130•400
x = 130•400/250 = 208mi
t = = 1.6 hr
