that #as 1!! ards in diameter. 2he started at the same spot, but the hare did not move

until the tortoise had a start of one eighth of the distance that is, the circumference of the

circle-. 2he hare held such a poor opinion of the otherBs racing abilit that he sauntered

along, nibbling the grass until he met the tortoise. At this point the hare had gone one si'th

of the distance. Co# man times faster than he #ent before must the hare no# run in order
