How many miles was Marco's journey to

What do you mean by that sir

Marco clearly lost his way home because there's no graph. marco is likely living under a bridge, because that graph is gone ... poor marco ... maybe some day they will find him ... but for now ... we just have to wait ... if only marco had been more responsible with the graph and had included it in his question ... (or you're just missing part of the question and it doesn't include a graph)
