Alight-year is the distance that light can travel in one year. if the sun is 1.5 x 10⁸ km away, how many light years is the sun from earth? assume that light travels at a speed of 3.0 x 10¹⁰ cm/s.

0.00001581 light years

Explanation:

distance divided by speed of light= 150,000,000/300,000= 500 seconds 8.3333

8.3 minutes

now divide this by 60 x 24 x 365.25. so you will get answer=
