In the movie Polar Express the hero boy character walks across the top of the train in order to return a lost ticket to another child. Instead he encounters a hobo.
Assume the train is traveling in a perfectly straight line, and both the train and boy maintain constant speeds. The boy's initial position is 1.5 m and the hobo's initial position is 17.2 m. If the train/hobo are moving at a constant velocity of 72 m/s, and the boy is walking at a constant velocity of 0.5 m/s, what position will they all have when the boy reaches the hobo? Round your answer to the nearest 1 m.
