A train leaves L.A. at 4:00am going 80 miles an hour, another train leaves New York at 8:00am going 90 miles an hour, where will they meet?
---------------------------
From LA to NY DATA:
rate = 40 mph ; time = x hrs. ; distance = 40x miles
---------------------------
From NY to LA DATA:
rate = 90 mph ; time = x+4 hrs ; distance = 90(x+4) miles
---------------------------
Comment: You need to post the distance from LA to NY
to get a solvable equation.
