saturn is approximately 1.4 x10^9 kilometers from the Sun. If light travels at approximately 3.0 x 10^5 kilometers per second, how long does it take light from the Sun to reach Saturn? Express your answer in scientific notation.

Mary,
I divided 1.4 x 10^9/3.0 x10^5=
4.7 x 10^4 sec

Mary,
I thought you take 10^95 or 10^4 is the exponent

drwls,
0.47*10^4 = 4.7*10^3
