**At 11AM a train traveling 57 mph leaves Chaney City for Atlantic City 543 miles south. At 1PM a train on a parallel track leaves Atlantic City for Chaney City and travels at 42 mph. At what time will they pass each other?**

I have 57x+42y=543 and x+2=y

and I solved for x and y. I got x=51/11 and y=73/11 but now I do not know what do do from here. Can someone please help me? Thank you!
