Here are the distances from each planet to the Sun, written in scientific notation:

  • Mercury: \(3.59 \times 10^7\) miles
  • Venus: \(6.72 \times 10^7\) miles
  • Earth: \(9.3 \times 10^7\) miles
  • Mars: \(1.42 \times 10^8\) miles
  • Jupiter: \(4.83 \times 10^8\) miles
  • Saturn: \(8.855 \times 10^8\) miles
  • Uranus: \(1.8 \times 10^9\) miles
  • Neptune: \(2.8 \times 10^9\) miles

Shortest and Longest Distance:

  • The shortest distance is Mercury: \(3.59 \times 10^7\) miles.
  • The longest distance is Neptune: \(2.8 \times 10^9\) miles.

Average Distance Calculation:

To find the average distance, we'll convert the scientific notation of the distances to a common unit and then average them:

\[ \text{Average distance} = \frac{(3.59 \times 10^7) + (6.72 \times 10^7) + (9.3 \times 10^7) + (1.42 \times 10^8) + (4.83 \times 10^8) + (8.855 \times 10^8) + (1.8 \times 10^9) + (2.8 \times 10^9)}{8} \]

Calculating the sum: \[ = 3.59 \times 10^7 + 6.72 \times 10^7 + 9.3 \times 10^7 + 1.42 \times 10^8 + 4.83 \times 10^8 + 8.855 \times 10^8 + 1.8 \times 10^9 + 2.8 \times 10^9 \]

This works out to be: \[ = 0.0359 + 0.0672 + 0.093 + 0.142 + 0.483 + 0.8855 + 1.8 + 2.8 \quad \text{ (in billions)} \]

\[ = 6.5066 \times 10^9 \quad \text{ (after converting to a common base of billion)} \]

Now, averaging: \[ \text{Average distance} = \frac{6.5066 \times 10^9}{8} \approx 8.133 \times 10^8 \text{ miles} \]

Adding Two Distances:

Let’s choose the distances from Earth and Jupiter:

  • Earth: \(9.3 \times 10^7\) miles
  • Jupiter: \(4.83 \times 10^8\) miles

Express Jupiter in the same terms (to be compatible): \[ 4.83 \times 10^8 = 48.3 \times 10^7 \]

Now, we can add them: \[ (9.3 \times 10^7) + (48.3 \times 10^7) = (9.3 + 48.3) \times 10^7 = 57.6 \times 10^7 \]

Converting back into scientific notation: \[ 57.6 \times 10^7 = 5.76 \times 10^8 \text{ miles} \]

Thus, the sum of the distances from Earth and Jupiter to the Sun is \(5.76 \times 10^8\) miles.
