To calculate the time it takes for light to reach us from the Sun, we can use the formula:
Time = Distance / Speed
Given:
Distance = 150 million km
Speed = 300,000 km/s
Plugging in the values:
Time = 150,000,000 km / 300,000 km/s
Time = 500 seconds
Therefore, it takes 500 seconds for light to reach us from the Sun.
