You need to multiply. When you do, you should get a distance of 11.8 inches.

ALL other answers are WRONG, so IGNORE them!!

You can set up a PROPORTION as follows: matrix%281%2C3%2C+%281.18+%2A+10%5E10%29%2FD%2C+%22=%22%2C+1%2F%281+%2A+10%5E%28-+9%29%29%29, with D being the distance. 

You now see that distance, or D =

This has been asked and answered several times.
Let's move on.
==============
There's no need to set up a proportion.
Multiply the 2 numbers.
Notice the seconds cancel, leaving the inches.
===============================================
A light-year us commonly used as the distance light travels in a year.
A light-foot is sometimes used (not my many) as the time for light to travel a foot. It's 1 nanosecond.
----------
---> 1 nanosecond = ~ 1 light-foot
