Time ≈ (1.5 x 10^11 m) / (3 x 10^8 m/s) = 0.5 x 10^3 seconds = 500 seconds.
Converting seconds to minutes: 500 seconds / 60 seconds/minute ≈ 8.33 minutes.
Among the given options, “About 8 minutes” is the closest and most accurate approximation for the time light takes to travel from the Sun to the Earth.
– Speed of light is approximately 3 x 10^8 m/s.
– Time = Distance / Speed.
