电话待机状态,电池可用24小时,如果持续使用,电池只能用3小时.如果刚充完电,开机了9小时,并且在这9小时中使用了60分钟,如果不再通话,可再待机多久?
答案：还可以再待机7小时,
设电量为1,待机每小时的用电量为1/24,通话每小时的用电量为1/3
后来这次 先待机9h,用电量为 1/24 * 9,然后通话 60分钟=1h,用电量为 1*1/3
用剩余的电量 1- 9/24- 1/3 除以待机每小时的用电量 1/24,结果为 7h.

大概翻译一下就是：Nikki有一部手机，这部手机如果不使用，可以开机24小时，如果冲完电就一直使用，可以用3小时。那么手机充电完毕到现在已经9个小时，其间使用了1个小时，问这部手机如果不使用，而一直保持开机，可以开机多长时间？
可以知道，手机每使用一小时，相当于开机没使用24/3=8。因此可以再开机不使用的时间是24-8=16.
不知道对不对。...
