We are given that the distance light travel is:

9.45 x 10^15 meters / year

And that there is:

3.15 x 10^7 seconds / year

So the distance light travels per second is:

distance = (9.45 x 10^15 meters / year) * (1 year / 3.15 x 10^7 seconds)

distance = 3 x 10^8 meters / second

The distance of the light travel per second is 3 x 10^8 meters/second

We are given that the distance light travel is

9.45 x 10^15 meters / year

And that there is

3.15 x 10^7 seconds / year

So the distance light travels per second is:

It is defined as the distance that light travels in free space in one second.

Therefore we get,

distance = (9.45 x 10^15 meters / year) * (1 year / 3.15 x 10^7 seconds)

distance = 3 x 10^8 meters / second.

Therefore the distance of the light is 3 x 10^8 meters/second.
