You can put this solution on YOUR website! passenger train 12mph faster than the speed of a freight train.
The passenger train travels 310 miles in the same time it takes the freight train to travel 250 miles. What is the speed of each train?
..
freight train speed be x
passenger train speed = x+12 mph
..
310 / x+12= 250 /x
310x= 250(x+12)
310x=250x+3000
310x-250x=3000
60x=3000
x=50 freight train speed
passenger train speed = x+12 = 50+12= 62 mph
