题目如下:Dara ran on a treadmill that had a readout indicating the time remaining in her exercise session. When the readout indicated 24 min 18 sec, she had completed 10% of her exercise session. The readout indicated which of the following when she had completed 40% of her exercise session?
10 min 48 sec
14 min 52 sec
14 min 58 sec
16 min 6 sec
16 min 12 sec
- 大概意思我看懂了,跑步机上剩下的时间是24min18sec的时候,Dara已经完成了10%
- 那完成40%的时候,跑步机指向多少分多少秒呢?这个楼主找不到思路的。不知道如何下手,希望大牛赐教啊。
- 12号就要考试了,模考分数却很低,努力了这么久,没看到出成绩,真是有点没信心了。顺便问下有没有人考试比模考高很多呢?
