The sun is about 1.5 × 108 kilometers from Earth. If light travels about 3 × 105 kilometers per second, about how many seconds does it take light from the sun to reach Earth?

OpenStudy (anonymous):

1.5 x 108 = 162. Do you mean how far in millions? Because, even if it were 162,000,000 km, it would still be incorrect, we are 149,600,000 km to the sun. Is there more to this question than what you wrote?
