Convert 1 second into day.

Options

A. `(1)/(86400)` Day
B. 24 day
C. `1/24` day
D. `1/3600` day

Answer

To convert 1 second into days, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the relationship between days, hours, minutes, and seconds**:
- 1 day = 24 hours
- 1 hour = 60 minutes
- 1 minute = 60 seconds

2. **Calculate the total number of seconds in one day**:
- First, convert days to hours:
\[ 1 \text{ day} = 24 \text{ hours} \]
- Next, convert hours to minutes:
\[ 24 \text{ hours} = 24 \times 60 \text{ minutes} = 1440 \text{ minutes} \]
- Finally, convert minutes to seconds:
\[ 1440 \text{ minutes} = 1440 \times 60 \text{ seconds} = 86400 \text{ seconds} \]

3. **Find the fraction of a day that 1 second represents**:
- Since 1 day = 86400 seconds, to find out how many days are in 1 second, we can set up the following equation:
\[ \text{Days} = \frac{1 \text{ second}}{86400 \text{ seconds/day}} \]
- This simplifies to:
\[ \text{Days} = \frac{1}{86400} \]

4. **Final Answer**:
- Therefore, 1 second is equal to \(\frac{1}{86400}\) days.

### Summary:
1 second = \(\frac{1}{86400}\) days.
