Given: The train traveled for 25 hours at a speed of 50 mph
Distance = (speed)(time) = (50 mph)(25 hours) = 1250 miles

So, we need to find a path to station W that is 1250 miles in length.
If we travel from station U to V to W, the total distance is 1250 miles

So the train must have started its journey at station U.
