Then he walks 1 mile east, and, finally, he walks 1 mile north to end up where he started, at his cabin. To his surprise, he finds a bear inside. What is the color of the bear? Ben: The bear must be a white polar bear because the hunter returns to his initial point after traveling 1 mile south, 1 mile east, and 1 mile north. Thisis possible only if the hunter starts his journey at the North Pole. Book Part North Pole Oxford University Press (via Crossref) 5 12 |
