Answer 1

Eight minutes

Explanation:

We know that the distance from the Sun to the Earth is 150 million km and light moves at 300000 kilometers/second. Therefore, we can calculate the time as follows:

`\begin{gathered} v=(d)/(t) \\ \text{ replacing} \\ 300000=(150000000)/(t) \\ t=(150000000)/(300000) \\ t=500\text{ s}\cdot\frac{1\text{ min}}{60\text{ s}}=8.33\text{ min} \\ t=8\text{ min} \end{gathered}`

So it takes about 8 minutes
