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.

Divide the separation distance by the speed of light, using scientific notation.

time=distance/speed 
I divided 1.4 x 10^9/3.0 x10^5=
4.7 x 10^4 sec 
Try again. You got the exponent wrong

answer=4.7 x10^3

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

0.47*10^4 = 4.7*10^3

I understand now. When i divided it gave me .047. Thank you for your help.
