◆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.
有兩個指針鐘,各具有時針、分針及秒針。
其中一個鐘運作完全正常,但另一個鐘壞了,運行的速度快了 20%。
現將兩者皆設置成十二點整,然後持續觀察直到以下狀況發生:
兩個鐘的秒針所在位置相同,且正常的鐘的分針位置和壞掉的鐘的時針位置相同。
試問在設定完成之後此狀況第一次發生在何時?
以十二小時制回答,略去秒數,如 01:23。

「持續觀察到」改成「持續觀察直到」好像比較好
