No such law exists. It's nothing more tan just a urban myth. In universities or college it is usually assumed (often told by the teacher during orientation) that after so many minutes, if they aren't in class you can leave without being marked absent.
In some places, it isn't a rule but the college/university may allow you to leave if the teacher doesn't arrive within 15 minutes.
In reality, you shouldn't leave unless been instructed by another member of staff or else otherwise. Teachers can be late due to various reasons like distance between building block or campuses, or stuck in traffic and can't get in on time.
If you did follow this, then you face the risk of being penalised by the college or university as it would be classed as 'bunking' and you would be marked as 'unauthorised absence'.
yes
A flight from Taiwan to Seattle takes approximately 12 hours and 49 minutes long. So, if you leave Taiwan at 8 pm, you will arrive in Seattle at about 8.49 am the next day.
For 18 people to arrive in one hour, one person must arrive every 3.3 minutes. The ninth person will arrive after approximately 27 minutes, meaning the first person would have to leave at that time. For the rest of the day to continue at the same rate, another person would have to leave every 3.3 minutes. Each person would remain in the store for approximately 27 minutes.
