Well, it is obvious that BabyG meant 10^8 and not 108. Anyway, the average distance, as Mr. X said, is almost 149,600,000 km. So all you have to do is this :
150,000,000 km ÷ 300,000 km per second = 8.333 minutes.
0.333 minutes x 60 seconds per minute = 19.98 seconds
So the answer is 8 minutes and roughly 20 seconds. Also considering that we're talking about average distance and light speed which is not quite 300,000 but 299,792.458 km per second.
It's not 1.512 x 108km, that would be a bit over 163 kilometers, which is obviously too little.
Light speed c is 299,792,458 m/s, and the distance between the earth and the sun is 149,597,870,700 meters. This means it takes about 8 minutes and 20 seconds for light from the sun to reach earth.
