To turn minutes into hours, we must to divide the minutes by 60. This is because 60 minutes make 1 hour. Thus, 120 minutes make 2 hours, 180 minutes make 3 hours, and so on.
When the desired transformation does not result in an integer value of time, care is needed in interpretation. For example, 150 minutes equals 2.5 hours, as 150 ÷ 60 = 2.5. This result is indicative of 2 hours and 30 minutes, as it represents 2 hours plus 0.5 hours, that is, 2 hours plus half an hour.

What is the relationship between minutes and hours?
Hours, minutes and seconds they are time measurement units. The relationship between these three units is as follows:
|
1 hour has 60 minutes. 1 minute has 60 seconds. |
This means that we can convert one unit of measurement to another as needed. Let's look at each conversion in more detail.
Do not stop now... There's more after the publicity ;)
How to convert minutes into hours?
Every 60 minutes makes 1 hour, consequently, to convert minutes into hours, it is necessary to divide the number of minutes by 60.
|
60 minutes → 1 hour 120 minutes → 2 hours 180 minutes → 3 hours 240 minutes → 4 hours |
In these examples, minutes indicated integer hour values. What if it doesn't? For example, 200 minutes is how many hours?
Note that 200 minutes is 180 minutes plus 20 minutes, that is, 200 minutes is 3 hours and 20 minutes.
Careful: When we perform the division by 60 to transform minutes into hours, it is necessary to pay attention to the interpretation of the decimal value.
In the previous example, we have that 200 ÷ 60 = 3.3333…. This result indicates 3 hours plus 0.33333... of hour. As \(0,333\ldots=\frac{1}{3}\), 200 minutes equals 3 hours plus a third of an hour (20 minutes).
Example: 90 minutes is how many hours?
note that 90 ÷ 60 = 1,5. This indicates that 90 minutes equals 1 hour plus 0.5 of an hour (that is, half an hour). Therefore, 90 minutes equals 1 hour and a half or 1 hour and 30 minutes.
How to convert hours into minutes?
Since 1 hour has 60 minutes. To convert hours into minutes, you need multiply the number of hours by 60.
|
1 hour → 60 minutes 2 hours → 120 minutes 3 hours → 180 minutes 4 hours → 240 minutes 5 hours → 300 minutes 6 hours → 360 minutes 7 hours → 420 minutes |
Example: How many minutes are there in 12 hours?
There are 720 minutes in 12 hours, as 12 × 60 = 720.

How to transform minutes into seconds?
As 1 minute has 60 seconds, to convert minutes into seconds, it is necessary to multiply the number of minutes by 60.
|
1 minute → 60 seconds 2 minutes → 120 seconds 3 minutes → 180 seconds 4 minutes → 240 seconds 5 minutes → 300 seconds |
Example: How many seconds are there in 15 minutes?
15 minutes have 900 seconds, as 15 × 60 = 900.
Observation: 1 hour has 60 minutes. To convert minutes to seconds, multiply the minutes by 60. Thus, 1 hour corresponds to 60minutes × 60 = 3600 seconds.

Solved exercises on converting minutes to hours
question 1
João watched a 3-hour live. This means that he watched her for a period of
a) 18,000 seconds.
b) 16,000 seconds.
c) 12,500 seconds.
d) 10,800 seconds.
e) 8300 seconds.
Resolution
3 hours have 3 × 60 = 180 minutes.
180 minutes equals 180 × 60 = 10,800 seconds.
Therefore, 3 hours have 10,800 seconds.
Alternative D
question 2
Consider the statements below about converting between units of time and classify each one as T (true) or F (false).
i. 480 seconds equals 10 minutes.
II. 24 hours have 1440 minutes.
III. 45 minutes have 2500 seconds.
The correct order is:
a) V-V-V
b) F-V-F
c) V-F-V
d) V-V-F
e) F-V-V
Resolution
Statement I is false, as 480 seconds corresponds to 8 minutes, since 480 ÷ 60 = 8 .
Statement II is true, as 24 × 60 = 1440 .
Statement III is false, as 45 minutes have 2700 seconds, since 45 × 60 = 2700 .
The correct order is F-V-F.
