Wash to Char train DATA:
rate = 60 mph: time = x hrs; distance = rt = 60x miles
-----------------
Char to Wash train DATA:
rate = 50 mph; time = x-1 hrs ; distance = rt = 50(x-1) miles
---------------------
Equation:
dist + dist = 500 miles
60x + 50x -50 = 500
110x = 550
x = 5 hrs
-----
x-1 = 4 hrs (time for the Char to Wash train
