The problem states: Saturn is approximately 1.4x 10 to the 9th power kilometers from the Sun. If light travels at approx. 3.0 x 10 to the 5th power kilometers per second, how long does it take light from the Sun to reach Saturn? Express your answer in scientific notation.

The answers are: 4.7 x 10 to the 4th power, 4700 sec, 4.7 x 10 to the 3rd, or 47 x 10 to the 3rd.

I used the formula t=d/r

1.4 x 10 to the 9th power divided by 3.0 x 10 to the 5th power leaves 0.4666 x 10 to the 4th power.

I think the answer is 4.7 x 10 to the 3rd power. Is this correct?
