You can put this solution on YOUR website! You can think of one train as standing still
and the other train moving at the sum of
their speeds
The formula for the moving train is km hrs
The trains will pass at 3 PM + 3 hrs, or 6 pm
You can also check answer this way:
slower train: km
faster train: km
OK
