Since "takes a passanger train 5 hr less time than it takes a freight train" this means that we have the equation:
Start with the distance-rate-time formula
Let's set up the equation for the passenger train
Now let's set up the equation for the freight train
Now replace "d" with
to both sides.
from both sides.
Combine like terms on the left side.
Divide both sides by
So it takes 15 hours for the freight train to arrive
Go back to the freight train speed equation
So the distance is 900 miles
