Answer:
True
Explanation:
1 light year is the distance travelled by light in one year
Distance of 1 light year
1 light year = 3×10⁸×365×24×60×60 m
Speed of light = 3×10⁸ m/s
300,000 light years = 300,000×3×10⁸×365×24×60×60
[tex]\text{time}=\frac{\text{Distance}}{\text{Speed}}\\\Rightarrow \text{time}=\frac{300,000\times 3\times 10^8 \times 365\times 24\times 60\times 60}{3\times 10^8}\\\Rightarrow \text{time}=300,000\times 365\times 24\times 60\times 60\ s\\\Rightarrow \text{time}=300,000\ years[/tex]
So, time taken by light to cover 300,000 light years is 300,000 years
