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?Question response areaSelect one option0.002 seconds5 seconds8 minutes and 20 seconds8 minutes and 33 seconds
Solution
To solve this problem, we need to use the formula for time which is distance divided by speed.
The distance from the Sun to Earth is 150,000,000 kilometers and the speed of light is 300,000 kilometers per second.
So, we divide 150,000,000 by 300,000 to get the time it takes for sunlight to travel from the Sun to Earth in seconds.
150,000,000 km ÷ 300,000 km/sec = 500 seconds
However, we usually express this time in minutes, not seconds. To convert seconds to minutes, we divide by 60 (since there are 60 seconds in a minute).
500 sec ÷ 60 = 8.33 minutes
So, it takes approximately 8 minutes and 20 seconds for sunlight to travel from the Sun to Earth. Therefore, the correct answer is "8 minutes and 20 seconds".
