Exercise 2

Just for the fun of it, someone in Beaufort, South Carolina, throws a message in a bottle into the sea. Some time later, someone in Perth, on the west coast of Australia, finds the bottle. Referring to Figure 3.20 and the fold-out map at the back of this book, can you trace the path the bottle probably took?
