D. `24 xx 100 xx 60 S`

Answer

To find out how many seconds are in one day, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the number of hours in a day**:
- We know that there are 24 hours in one day.
\[ \text{Hours in one day} = 24 \text{ hours} \]

2. **Convert hours to minutes**:
- We know that each hour has 60 minutes.
\[ \text{Minutes in one hour} = 60 \text{ minutes} \]

3. **Calculate the total minutes in one day**:
- To find the total minutes in one day, multiply the number of hours by the number of minutes in an hour.
\[ \text{Total minutes in one day} = 24 \text{ hours} \times 60 \text{ minutes/hour} = 1440 \text{ minutes} \]

4. **Convert minutes to seconds**:
- We know that each minute has 60 seconds.
\[ \text{Seconds in one minute} = 60 \text{ seconds} \]

5. **Calculate the total seconds in one day**:
- To find the total seconds in one day, multiply the total minutes by the number of seconds in a minute.
\[ \text{Total seconds in one day} = 1440 \text{ minutes} \times 60 \text{ seconds/minute} = 86400 \text{ seconds} \]

### Final Answer:
Thus, one day is equal to **86400 seconds**.
