To convert 11.3 light years into seconds, follow these steps:

1. **1 light year** is the distance that light travels in one year. Since the speed of light is approximately \( 299,792,458 \) meters per second, this means that in one year, light travels:

   \[
   1 \text{ light year} = 299,792,458 \times 31,536,000 \text{ seconds/year} 
   \]
   where 31,536,000 is the number of seconds in a year.

2. Multiply the speed of light by the number of seconds in a year:
   \[
   1 \text{ light year} = 9.4607 \times 10^{15} \text{ meters}
   \]

3. Now, to find how many seconds it would take for light to travel 11.3 light years, multiply the number of seconds in a year by 11.3:

\[
11.3 \text{ light years} \times 31,536,000 \text{ seconds/year} = 356,356,800 \text{ seconds}.
\]

So, light travels 11.3 light years in **356,356,800 seconds**.
