Answer 1

To estimate the distance of Uranus from the Sun in astronomical units (AU), we can look at the distances of Saturn and Neptune, which are 9.5 AU and 30 AU, respectively.

Since Uranus is located between Saturn and Neptune, a reasonable estimate for its distance would be the average of 9.5 AU and 30 AU.

To find the midpoint: \[ \text{Midpoint} = \frac{9.5 + 30}{2} = \frac{39.5}{2} = 19.75 \text{ AU} \]

Since we are asked for a reasonable estimate, we can round this to 20 AU.

So the correct response is: 20
