Q) Light travels 300,000 km per second. The sun is 93 *10^6 miles from the Earth. How long does it take sunlight to reach the Earth? (Note: you need to convert the distance to the sun to kilometers before calculating the time.) Express your answer to the nearest minute.
Ans. Light travels 300,000 km/sec
Distance between the Sun and the Earth is 93 * 10^6 miles = 149.67 * 10^6 km.
Time take sunlight to reach the Earth is = 149.67 * 10^6 km / 300,000 km/sec = 498.9 sec = 499 sec.
499 sec = 8 minute 19 second.
So, sunlight take 8 minute 19 second to reach the Earth.
