<PRE><B>Question 921118</B>
a train leaves a station and travels east at 40km/h three hours later a second train leaves on a parallel track traveling east at 60km/h how far away from the station do the trains meet?
------------------
1st train DATA:
rate = 40 km/hr ; time = x hrs ; distance = 40x km
-----
2nd train DATA:
rate = 60 km/hr ; time = x-3 hrs ; distance = 60(x-3) km
-----
Equation:
40x = 60x - 180
-20x = -180
x = 9 hrs (time for later train to catch up to earlier train)
------------
Cheers,
Stan H.
