How many minutes are in 1 day?

In one day, there are 24 hours. Each hour has 60 minutes, so to find the total number of minutes in a day, you can multiply 24 hours by 60 minutes per hour. This calculation results in 1,440 minutes.

Additionally, when converting minutes to seconds, it's important to know that each minute contains 60 seconds. Therefore, when you multiply the 1,440 minutes by 60 seconds per minute, you arrive at a total of 86,400 seconds in one day.

This understanding of how to perform the conversion illustrates why 1,440 minutes equals 86,400 seconds, making the correct choice a reliable answer based on fundamental time measurements.
