Mr. Greenwich owns a rugged cottage that is without power. There is a grandfather clock in it which he frequently forgets to wind. One day when this happened, he went to Professor Quantum's to check the time. When Mr. Greenwich returned, the first thing he did was set his grandfather clock to the correct time. Since he does not have a TV, telephone, or radio, how could he set his clock without knowing the length of the trip to Professor Quantum's?
