Given
The Sun is d=150 million kilometers away from Earth.
Light travels at v=3 × 10^5 m/s.
To find
How long does it take for light to reach Earth from the Sun?
Explanation
We know
Time taken is given by
[tex]\begin{gathered} t=\frac{d}{v} \\ \Rightarrow t=\frac{150\times10^6}{3\times10^5} \\ \Rightarrow t=500sec \end{gathered}[/tex]Conclusion
The time taken is D.500 sec
