the speed of light is marked down as 299,792,458 metres per second (300,000 Kilometers per second). The Sun is about 149.6 million kilometers away (149,600,000 Kilometers).
Dividing the distance by the speed will give us the time in seconds, thus:
149,600,000 / 300,000 = 498.7
Therefore it takes Light roughly 500 seconds to reach the earth from the sun. Thats 8 minutes and 20 seconds.
