i cannot seem to make this work. If two trains leave the station at the same time, one traveling north and the other traveling south. the express travels 14 mph faster than the local. after 3 hours they are 315 miles apart. what is the rate of each train.
this is what I figured:

r * t= d
y=x+14.
3x + 3y= 315
