How many seconds are there in a day?

To determine how many seconds are in a day, we can break it down using the measurements of time.

We start with the number of seconds in one minute, which is 60. Next, we know that there are 60 minutes in one hour. Therefore, the total number of seconds in one hour is calculated as follows:

60 seconds/minute × 60 minutes/hour = 3,600 seconds/hour.

Then, we recognize that there are 24 hours in a day. To find the total number of seconds in a day, we multiply the number of seconds in one hour by the number of hours in a day:

3,600 seconds/hour × 24 hours/day = 86,400 seconds/day.

This confirms that the total number of seconds in one day is indeed 86,400.
