To calculate the time it takes for light to travel from the sun to the earth, we can use the formula:
time = distance / speed
Given:
Distance = 1.5 x 10^11 meters
Speed = 3.0 x 10^8 meters per second
Plugging in the values:
time = (1.5 x 10^11) / (3.0 x 10^8)
time = 5 x 10^2 seconds
Therefore, it takes approximately 500 seconds for light to travel from the sun to the earth.

500 seconds can be written in scientific notation as 5 x 10^2 seconds.

I apologize for the mistake. Let me correct the calculation:
\[time = \frac{1.5 \times 10^{11}}{3.0 \times 10^8} \\
time = \frac{1.5}{3} \times \frac{10^{11}}{10^8} \\
time = 0.5 \times 10^{3} \\
time = 5 \times 10^{2} \text{ seconds}\]
Therefore, it takes 5 x 10^2 seconds (500 seconds) for light to travel from the sun to the earth.
