The tortoise and the hare agree to a re-match. As they begin the race, the tortoise plods along slowly but confidently at 2 ½ mph. The hare zips ahead at 8 ½ mph, determined not to repeat his original mistake…and he doesn’t! The hare never slows down and reaches the finish line 45 minutes (3/4 of an hour) before the tortoise. How long did the tortoise run?
