◆CLOCKS
There are two analog clocks with hour, minute and second hands.
One of them works correctly and the other one is broken, moving 20% faster.
Both of them are set to 12:00 and observed until their second hands are
at the same angle and the minute hand of the correct clock is at the same
angle with the hour hand of the broken clock.
What is the time when this first happens after they are set?
Enter your answer in 12-hour format without seconds, like 01:23.
有两个指针钟,各具有时针、分针及秒针。
其中一个钟运作完全正常,但另一个钟坏了,运行的速度快了 20%。
现将两者皆设置成十二点整,然后持续观察直到以下状况发生:
两个钟的秒针所在位置相同,且正常的钟的分针位置和坏掉的钟的时针位置相同。
试问在设定完成之后此状况第一次发生在何时?
以十二小时制回答,略去秒数,如 01:23。

“持续观察到”改成“持续观察直到”好像比较好
