please help I'm really bad at math and I keep getting half way there on everything but i'm behind so I can't afford to be so slow in this =p =(

anonymous · Answer

rate times time is distance.
Let r be the speed in mph for the west bound train.
Then r-14 is the speed of the slow train that is east bound.
(r+(r-14))*4 = 640
Solve the above for r.
r = 73 mph

So I plug 73 into the equation or 73 is the answer?
