Question
The distance from the Sun to Earth is 150 000 000 kilometres.Sunlight travels at a speed of 300 000 kilometres per second.How long does it take sunlight to travel from the Sun to Earth?
Solution
To calculate the time it takes for sunlight to travel from the Sun to Earth, we need to divide the total distance by the speed of light.
Here are the steps:
- Distance from Sun to Earth = 150,000,000 km
- Speed of sunlight = 300,000 km/second
So, Time = Distance / Speed
Time = 150,000,000 km / 300,000 km/second
After performing the division, we find that it takes approximately 500 seconds for sunlight to travel from the Sun to Earth.
