Answer
8 minutes and 19 seconds for light from the sun to reach earth
Work Step by Step
The speed of light in a vacuum is approximately 299,792,458 meters per second. Since the distance from the sun to the Earth is approximately 93 million miles, or approximately 149.6 million kilometers, we can calculate the time it takes light from the sun to reach Earth as follows:
Distance = Speed x Time
149.6 million km = 299,792,458 m/s x Time
Solving for Time, we get:
Time = Distance / Speed
Time = (149.6 x 10^6 km) / (299,792,458 m/s)
Time = 499.004 seconds or approximately 8 minutes and 19 seconds
Therefore, it takes approximately 8 minutes and 19 seconds for light from the sun to reach Earth.
