You don’t need any of the numbers to answer the question. Ask yourself, where is the fast train when the trains meet? How about the slow train?
When the 2 trains meet, the fronts of each train are the same distance from Sydney! The back of the fast passenger train is slightly closer to Sydney, and the back of the slow freight train is slightly further away.
