Well, the speed of light is 299,792,458 m/s (meters per second, not miles).

Now here's where things get a little complicated. Earth's orbit around the sun is not a circle, it's an oval. I don't know the CURRENT distance between the sun and Earth, but the AVERAGE distance is 149,600,000,000 meters.

Well distance equals speed times time, so time equals distance over speed. So we do 149,600,000,000 meters divided by 299,792,458 m/s which gives us 499 seconds, otherwise known as 8 minutes 19 seconds. That's how long it takes light to go from the sun to Earth.
