If you earn $1 a second, you can calculate your total earnings for one day as follows:
- There are 60 seconds in a minute.
- There are 60 minutes in an hour.
- There are 24 hours in a day.
Now, multiply these together to find the total number of seconds in a day:
\[ 60 \text{ seconds/minute} \times 60 \text{ minutes/hour} \times 24 \text{ hours/day} = 86,400 \text{ seconds/day} \]
Since you earn $1 for each second, your total earnings for the day would be:
\[ 86,400 \text{ seconds} \times 1 \text{ dollar/second} = 86,400 \text{ dollars} \]
So, by the end of the day, you would have $86,400.
