To determine how many minutes are in one day, we need to follow these steps:
1. Understand the basic conversions:
- 1 day is equivalent to 24 hours.
- 1 hour is equivalent to 60 minutes.
2. Calculate the total number of minutes in one day:
- Since each hour has 60 minutes, multiply the number of hours in a day by the number of minutes in an hour:
[tex]\[
\text{Total minutes in one day} = \text{Number of hours in one day} \times \text{Number of minutes in one hour}
\][/tex]
3. Perform the multiplication:
[tex]\[
\text{Total minutes in one day} = 24 \times 60
\][/tex]
4. The result of this multiplication gives us:
[tex]\[
24 \times 60 = 1440
\][/tex]
Thus, there are 1440 minutes in one day.
So, the correct answer is:
C. 1440 minutes
