Let's look at how to translate minutes into hours and vice versa. To begin with, we agree that we will need knowledge of arithmetic. After all, one cannot do without calculations. If you can’t do them in your mind or on a piece of paper, then use a calculator. Below will be presented almost all options for how to convert minutes to hours.
From ancient times to the present
Look at the dial. It has 60 divisions, i.e. 60 seconds (minutes). Those who are friends with mathematics have long noticed that this science is like a trick, mysticism, thereby amusing. Ancient people were no more stupid than our contemporaries, on the contrary, they even succeeded in something.
What we have today:
- 1 hour is 60 minutes;
- 1 minute equals 60 seconds;
- 1 hour contains 3600 seconds.
Of course, 3600 seconds was obtained by multiplying 60 minutes * 60 seconds. Let's take another look at the dial: for example, the hour (short hand) is at 12, and the minute (long) indicates that it is now 20 minutes. That is twenty minutes to one. Now let's look at how to convert minutes to hours with this example.
Simple and complex calculations up to 1 hour
Remember the arithmetic in elementary school and grade 5: there were fractions. What are we getting at? 1 hour = 60 minutes And we only have 20 minutes. It may be incorrectly noted that only 20/60 hours have passed. But we know that fractions can be reduced. Let's do that:
20/60 = 1/3.
In total 1/3 hours have passed, or, if we divide, then 0.33.
Consider another option: what does a quarter of an hour mean? How to convert minutes to hours vice versa?
1/4 hours = 15 minutes. How did it happen?
15 min. / 60 min. = 1/4.
How to write down 10 minutes in hours? The solution technique is identical:
10 min. / 60 min. = 1/6 hours = 0.167 hours. It is clear that such a record is incorrect, therefore it is recommended not to translate 10 minutes.
Over an hour
Many of us saw how, for example, it was written in the annotation for the film, its duration: 150 min. How to convert minutes to hours in this case? Please note that there will be no more fractions. Why? Because in the previous section we were talking about time that lasted less than 1 hour. And now on the contrary. It will be easy to look on the one hand, but actually more difficult.
So, back to 150 minutes. In order not to think for a long time, let's mentally summarize 60 minutes until we get to the cherished 150: 60 min. + 60 min. = 120. We need to stop, because if we add another 60 minutes, it will be 180, and after all, we have a movie that takes only 150 minutes. Back to our 120 minutes. Of course, this is 2 hours. And now we subtract 120 from 150 minutes. We get 30.
It can be done differently. Stop for 120 minutes and mentally catch up with the missing half an hour. Here is the result: 150 min. = 2 hours 30 minutes = 2.5 hours.
And how to get from 1.5 hours of a minute? Immediately imagine 1 hour 30 minutes: 60 + 30 = 90 minutes.
Another option: the arithmetic fraction is one whole and five tenths, which after the conversion has the form: 15/10 = 3/2. In fact, 1.5 hours is 3/2 hours.
Imagine a lesson in class 3, which is associated with fractions. There were still color pictures that clearly showed what 5/6 or 1/2 means.
Why are such difficulties required?
Imagine studying a train schedule. As a rule, they write, for example, travel time: 1 hour 5 minutes. Everything seems to be clear. But let's imagine how many minutes it is? 65 minutes Other: 2 hours 35 minutes? Let's calculate:
2 hours = 120 minutes, add another 35 minutes. In total: 120 + 35 = 155 min.
So we looked at how to convert minutes to hours and vice versa. In order to be able to quickly calculate, it is advisable to know the basics of mathematics. If you can’t mentally count, you should solve the problem on a piece of paper.
