To calculate how many seconds are in a 24-hour day, we start by considering the number of seconds in one minute and the number of minutes in one hour.
There are 60 seconds in a minute, and there are 60 minutes in an hour. Therefore, in one hour, there are:
- 60 seconds/minute × 60 minutes/hour = 3600 seconds/hour
Next, since there are 24 hours in a day, we multiply the number of seconds in one hour by the number of hours in a day:
- 3600 seconds/hour × 24 hours/day = 86,400 seconds/day
So, in total, there are 86,400 seconds in a 24-hour day.
