Light travels at a rate of 3 * 10 ^ 8 meters per second If the earth is 1.5 * 10 ^ 11 meters away from the sun, how long does it take for light to travel from the sun to the earth?

Answer 1

To calculate the time it takes for light to travel from the sun to the earth, we can use the formula:

Time = Distance / Speed

Where:
Distance = 1.5 * 10^11 meters
Speed = 3 * 10^8 meters per second

Plugging the values into the formula:

Time = (1.5 * 10^11) / (3 * 10^8)
Time = 5 * 10^2 seconds

Therefore, it takes 500 seconds for light to travel from the sun to the earth.
