kilometres is metres. Three hundred million metres is metres. , so it takes about 499 seconds, or minutes for the light to arrive at the earth, roughly speaking.

The sun is approximately 1.496 * 10^8 kilometres from earth. If light travels at three hundred million metres per second, how long does it take for light to travel from the sun to the earth ?
--------------------------------------
First:
Change the kilometers to meters.
(1.496x10^8 km)(1000 meters/km) = 1.496x10^11 meters
-----------------
Divide distance by the speed of light:
(1.496x10^11 meters m) / (3.00x10^8 m/s) = 4.9867x10^2 seconds
= 8.111 minutes
==================
