PLZ HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! The speed of a passenger train is 12 mph faster than the speed of a freight train. The passenger train travels 250 miles in the same time it takes the freight train to travel 190 miles. Find the speed of each train. i got help but idk witch # is 4 witch. 250/(x+12)=190/x cross multiply to get 250x=190(x+12) 250x=190x + 190(12) 60x=190(12) etc x=38 so speeds are 38 and 50 mph
