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.
Light travels at a rate of 3.0 x 10^8
meters per second. If the earth is 1.5 x 10^11
meters away from the sun, how long does it take for light to travel from the sun to the earth?

whats that in scientific notanion
500 seconds can be written in scientific notation as 5 x 10^2 seconds.
are you sure
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.
\[time = \frac{1.5 \times 10^{11}}{3.0 \times 10^8} \\
time = \frac{1.5}{3} \times \frac{10^{11}}{10^8} \\
time = 0.5 \times 10^{3} \\
time = 5 \times 10^{2} \text{ seconds}\]
Therefore, it takes 5 x 10^2 seconds (500 seconds) for light to travel from the sun to the earth.
