Answer:

497.01 seconds will it take light to move a distance of [tex]1.49\times 10^8 km [/tex]from the Sun to the Earth.

Explanation:

Speed of the light = 299,792,458 m/s

Time taken by the light to cover [tex]1.49\times 10^8 [/tex] kilometer = T

[tex]1.49\times 10^8km=1.49\times 10^{11} m[/tex]

Speed=[tex]\frac{Distance}{Time}[/tex]

[tex] 299,792,458 m/s=\frac{1.49\times 10^{11} m}{T}[/tex]

[tex]T=497.01 seconds[/tex]

497.01 seconds will it take light to move a distance of [tex]1.49\times 10^8 km [/tex]from the Sun to the Earth.
