to solve this you need to know distance = rate*time each car has its own distance, rate, and time set up a table with info you know rate time distance car1 x 2 2*x car2 x+12 2 2*(x+12) we also know total distance is 380 2x + 2(x+12) = 380 solve for x distribute and add like terms once you know x you know the rate of slower car to find rate of faster car add 12
