<PRE><B>Question 1144051</B>
Two trains left a station at the same time. One traveled north at a certain speed and the other traveled south at twice that speed. After 4 hours, the trains were 600 miles apart. How fast was each train traveling.
F = faster speed
S = Slower speed
-------
600/4 = 150 = the sum = F + S
F + S = 150
F = 2S
----------
2S + S = 150
S = 50 mi/hr
F = 100 mi/hr
==================================
600=2x+4
296=2x
x=298 miles per hour and 149 miles per hour???</PRE>
