About 8.3 minutes
Explanation:
Use the formula for velocity as the distance covered by the light divided the time it takes: " alt="velocity=\frac{distance}{time}" />" />
Use the information about the speed of light in vacuum:
and the information you are given regarding the distance between Sun and Earth:
to solve the first velocity equation for the unknown time "t":
we can convert second into minutes by dividing by 60: 500 s = 500/60 minutes = 8.3333... minutes
