## The light from the sun reaches the earth’s surface in about  _______________

1. 8 minutes 20 Seconds
2. 5 minutes 10 Seconds
3. 10 minutes and 30 Seconds
4. 15 minutes and 40 seconds

The correct option is (A): 8 minutes 20 Seconds

## Detailed Explanation by Teachoo

• 8 minutes and 20 seconds
• This is the average time it takes for sunlight to travel from the Sun to the Earth, according to NASA and other sources. The Sun is about 150 million kilometers (93 million miles) away from the Earth, and light travels at about 300,000 kilometers (186,000 miles) per second. So if we divide the distance by the speed, we get about 500 seconds, or 8 minutes and 20 seconds. This is correct.✅
• 5 minutes and 10 seconds
• This is not the correct time it takes for sunlight to reach the Earth. This would be true only if the Sun was much closer to the Earth, about 93 million kilometers (58 million miles) away. But the Sun is much farther than that, so it takes longer for its light to reach us. This is incorrect .❌
• 10 minutes and 30 seconds
• This is not the correct time it takes for sunlight to reach the Earth. This would be true only if the Sun was much farther from the Earth, about 189 million kilometers (117 million miles) away. But the Sun is much closer than that, so it takes less time for its light to reach us. This is incorrect .❌
• 15 minutes and 40 seconds
• This is not the correct time it takes for sunlight to reach the Earth. This would be true only if the Sun was very far from the Earth, about 282 million kilometers (175 million miles) away. But the Sun is much closer than that, so it takes much less time for its light to reach us. This is incorrect .❌
