roughly 30 cm
distance= speed of light x time
distance= 299792458m/s x 1/1000000000= .0299m
voila

light travels at around 3 *10^8 metres per second
so in 1 nanosecond it will travel around 30 cm

the speed of light is c= 3*10^8m/s
in a nanosecond d = spped * time
here distance = 310^8*10^-9 =3 10^-1 m = 0.3m

it depends on the media that the light is in.
For Instance, light travels slower in air than a vacuum.
and light travels even slower in a fiber optic tube.

One light-nanosecond is 0.3 metres, or about one foot.

light travels 300,000 km/s = 3*10^5 km/s and 1s=10^9 ns
So it travels 3*10^-4 km. 1km = 10^3 m so it travels 0.3m
