<PRE><B>Question 274000</B>
at noon a train leaves washington d.c. headed for charleston south carolina, a distance of 500 mi. the train travels at a speed of 60mph.
---------------------------------------
at 1 pm a second train leaves charleston headed for washington dc traveling at 50mph . 
---------------------------------------
how long after the train leaves charleston will the 2 trains pass each other
---
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
