一项包括跑步和自行车的竞赛运动,金骑自行车的速度比跑步快30公里/时.如果金用48分钟跑步,然后用它(前面跑步的时间)三分之一的时间接着来骑车,以此来完成60公里的赛程,问她跑步的速度是多少?(意译)
(假设跑步速度为 V km/h
V x 48/60 + (1/3 x 48/60) x (V + 30 )= 60
解方程得到 V = 48.75公里/时,另:跑了 39公里,骑自行车 21公里.供参考)

一个冬季两项事件涉及到跑步和骑自行车。金可以循环30公里/小时的速度比她快
跑步。如果金花了48分钟的跑步,并尽可能多的时间的三分之一,再骑自行车
占地总距离60公里,她可以运行的速度有多快?
