Thank you for the help! Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! You can think of this as one of the trains standing
still and the other one traveling at the sum of their speeds
-----------------------------
Let = time in hrs for the trains to be 354 km apart
They will be 345 km apart in 3 hrs
-------------------------------------
( I used because it makes the time come out a whole number )
check answer: km
and km
and
OK
