Answer:

[tex]1.86\cdot 10^{-4} mi[/tex]

Explanation:

Light travels at constant speed, so we can use the formula

[tex]d=vt[/tex]

where

d is the distance travelled

[tex]v=186000 mi/s = 1.86\cdot 10^5 mi/s[/tex] is the speed of light

[tex]t=1ns=1\cdot 10^{-9}s[/tex] is the time we are considering

Substituting the numbers into the formula, we find

[tex]d=(1.86\cdot 10^5 mi/s)(1\cdot 10^{-9} s)=1.86\cdot 10^{-4} mi[/tex]
