Final answer:
Neptune is 20 times farther from Earth than Mercury is. By dividing the distance to Neptune (2,700,000,000 miles) by the distance to Mercury (135,000,000 miles), we determine this ratio.
Step-by-step explanation:
The question asks to calculate how many times farther it is from Earth to Neptune than it is from Earth to Mercury. Given that Neptune is about 2,700,000,000 miles away and Mercury is about 135,000,000 miles from Earth, we simply divide the distance to Neptune by the distance to Mercury to get the ratio.
To find out how many times farther Neptune is from Earth compared to Mercury:
- Distance to Neptune: 2,700,000,000 miles
- Distance to Mercury: 135,000,000 miles
We divide the distance to Neptune by the distance to Mercury:
2,700,000,000 miles ÷ 135,000,000 miles = 20
Therefore, it is 20 times farther from Earth to Neptune than it is from Earth to Mercury.
