Section outline

  • How's it going math scholars? In today's topic we're going to talk about patterns and time, different time patterns. And if you focus your attention real quickly on this section right here you'll see that I have a basic pattern set out for you. This is 915, 925, 935, 945, 955 and a blank slot for our next time that we should put in there. And we're going to learn how to find that next time and how to find the pattern that exists between all these different times. Now some of you guys might be already noticing hey there's a 1, 5, 2, 5, 3, 5, 4, 5, 5, 5, 5 in the 10s column, 10s unit place of the minutes. So I wouldn't suggest that it's probably 10 minutes right that the difference between in this 10 minutes. But some of you guys were a little bit more skeptical and very much want to inquire into really if this is the truth, we'll want some mathematical proof and I'm going to offer you some proof. So we're going to find the difference. So I'm going to think about real quickly, what is the difference between 915 and 925? And I see that that difference is 10 minutes. And what's the difference between 925 and 935? And difference once again is 10 minutes. 935 and 945 is another 10 minutes. So the difference between all these five different time points is 10 minutes. Make sure that you're finding the time difference between each of these two. Sometimes it's easy to do this one and then forget about it and then do this one because you're thinking, oh I already covered 925 but you can't forget about this gap. So we see that the difference is 10 minutes, which means that the difference between our mystery one here and 955 should also be 10 minutes. So some of you guys are probably thinking, I'll just add 10 minutes. And I'm going to add 10 minutes. And after I write this, you're probably thinking something is a little fishy here. Something is a little bit wrong. I added 10 minutes, right? One from 5, 55 to 65. Well, I did do something wrong. I did it on purpose. It's probably because, and you know I did something wrong, probably because you're just geniuses at time already. But you'll notice that 65 minutes and hour is only 60 minutes. How do I have 65 minutes? Which means that when I add 10 minutes, 60 of these minutes, 60 out of these 65 can turn into another hour, which I can add to the 9. And that's exactly what I'm going to do. I've added an hour to my 9, so it's now 10 o'clock. And if I take 60 away from here and add it, what how many minutes do I have left? I have exactly five minutes left. And now I'm at 10-0-5. So those should be all the skills that you need. Remember, the key here is to find the difference between each two numbers that are side by side. And try to figure out if that's the same pattern that you see between all the other two numbers that are together. And if you can conclude that that's the same pattern, then you can find any blank, any question mark that is not you. Good luck!
    数学爱好者们,大家好!今天我们要讨论的是模式和时间,不同的时间模式。请大家快速关注一下这里的这个部分,你会看到我为大家设置了一个基本模式。这里是9:15、9:25、9:35、9:45、9:55,还有一个空白位置,我们需要填入下一个时间。我们将学习如何找到下一个时间以及如何找到这些不同时间之间存在的模式。有些人可能已经注意到,分钟的十位上有1、5、2、5、3、5、4、5、5、5。所以我认为它们之间的差异可能是10分钟。但是有些人可能比较怀疑,非常想探究真相,他们想要一些数学证明,我会提供一些证明。我们将找出差异。我将快速思考,9:15和9:25之间有什么差异?我看到这个差异是10分钟。9:25和9:35之间有什么差异?差异再次是10分钟。9:35和9:45之间又是10分钟。因此,这五个不同时间点之间的差异都是10分钟。确保你找到每两个时间点之间的差异。有时很容易只计算一次,然后忘记,然后计算下一次,因为你认为,哦,我已经计算了9:25,但你不能忘记这个间隔。我们看到差异是10分钟,这意味着我们这里的未知时间和9:55之间的差异也应该是10分钟。有些人可能在想,我只需要加上10分钟。我要加上10分钟。在我写完之后,你可能会觉得有些不对劲。有些地方不太对。我加上了10分钟,对吗?从55分到65分。嗯,我确实做错了。我是故意做错的。可能是因为,你知道我做错了,可能是因为你们已经是时间计算的天才了。但是你会注意到,65分钟,一个小时只有60分钟。我怎么会有65分钟?这意味着当我加上10分钟时,这65分钟中的60分钟可以变成另一个小时,我可以加到9上。我将要做的是,我给9加上了一个小时,所以现在是10点。如果我从这里减去60分钟并加上它,我还剩下多少分钟?我正好剩下5分钟。现在是10:05。这些应该是你需要的所有技能。记住,这里的关键是找到每两个相邻数字之间的差异。并尝试找出你看到的其他两个相邻数字之间是否是相同的模式。如果你能得出结论,这是相同的模式,那么你就可以找到任何空白,任何问号。祝你好运!
