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 10^9-5 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.
To find out how long it takes light from the Sun to reach Saturn, we can divide the distance between them (1.4 x 10^9 kilometers) by the speed of light (3.0 x 10^5 kilometers per second).
To calculate this, we can use the formula: Time = Distance / Speed.
So, the calculation would be:
Time = (1.4 x 10^9 kilometers) / (3.0 x 10^5 kilometers per second)
Time = (1.4 / 3.0) x (10^9 / 10^5) seconds
Time = 0.4666667 x 10^4 seconds
Since the resulting time is not in scientific notation, we can write it in scientific notation as follows:
Time ≈ 4.67 x 10^3 seconds
Therefore, it takes approximately 4.67 x 10^3 seconds for light from the Sun to reach Saturn.
