某一点就睡着了.当兔子醒来时,发现乌龟已领先500米,于是奋起直追.然而当乌龟到终点时,兔子仍落后10米,兔子懊悔不已,兔子在睡觉的时候乌龟跑了多少米?这题好难,
The hare and the tortoise meet 1000 meters race,rabbit's speed is the speed of 5 times,they also run,the tortoise running,lightly rabbit ran a little sleep.When the rabbit wakes up,found that the tortoise had a lead of 500 meters,then do all one can to catch up.However when the turtle to the end,the rabbit was still behind the 10 meters,the rabbit regret,the rabbit was sleeping when the tortoise run many meters?
兔子和乌龟相约进行1000米赛跑,兔子的速度是乌龟速度的5倍,它们同时起跑,乌龟不停地跑,轻敌的兔子跑到某一点就睡着了.当兔子醒来时,发现乌龟已领先500米,于是奋起直追.然而当乌龟到终点
假设兔子睡觉的点是X米,乌龟的速度是V,那么兔子的速度是5V,现在可得到下列算式
(1000-X-10)/5V=(1000-500-X)/V
由上可算出X=377.5
所以兔子睡觉时候乌龟跑了377.5+500=877.5米
