What would happen if the race was only a 20 meter race? If Andy and Barry were to run, would that mean Barry ran 0 meters? I think not. <br /><br />I think that Barry runs 80% of Andy's distance and Carl runs 80% Barry's distance. Which means when Andy finishes, carl will be 36 meters behind.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3802979373213475425.post-28242237847968765202011-06-22T14:53:29.489+05:302011-06-22T14:53:29.489+05:30right...40meters...>>exact answerright...40meters...>>exact answerAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-3802979373213475425.post-2013523575267273552011-04-24T12:41:00.453+05:302011-04-24T12:41:00.453+05:3040m
