Answer:
29 AU
Step-by-step explanation:
In the problem, we have:
- Distance between the Earth and the Sun: 1 AU
- Distance between Neptune and the Sun: 30 AU
The Earth is located between the Sun and Neptune, therefore its distance from Neptune can be calculated as the difference between the distance between Neptune and the Sun and the distance between the Earth and the Sun:
d = 30 AU - 1 AU = 29 AU
