Answer:

8.33 minutes

Explanation:

Distance between Earth and Sun = 1.5×10¹¹ m

Speed of light = 3×10⁸ m/s

Time = Distance / Speed

[tex]\text{Time taken}=\frac{1.5\times 10^{11}}{3\times 10^8}\\\Rightarrow \text{Time taken}=500\ seconds[/tex]

[tex]500\ seconds=\frac{500}{60}=8.33\ minutes[/tex]

∴ Time it takes for sunlight to reach the Earth is 8.33 minutes.
