<PRE><B>Question 647172</B>
A train leaves NYC for Washington DC traveling at 90 mph. At the SAME TIME, a train leaves Washington DC for NYC traveling at 95 mph. If NYC and Washington DC are 462.5 miles apart, how long will it take before the two trains meet? 
-------
NYC to DC DATA:
rate = 90 mph ; time = d/r = x hrs ; distance = 90x miles
-------------------------
DC to NYC DATA:
rate = 95 mph ; time = d/r = x hrs ; distance = 85x miles
-----
Equation:
distance + distance = 462.5 miles
-----
90x + 85x = 462.5
------
175x = 462.5
x = 2.64 = 2 hrs 39 minutes(time before the 2 trains meet)
===============================
