Answer:

B. 5.9 X 10^9

Explanation:

For this question, we assume the following:

•2.3 x 1014 inches is actually 2.3 x 10^14 inches.

•3.9 x 104inches is actually 3.9 x 10^4inches

We now calculate thus;

The average distance in km would be 2.3 x 10^14/3.9 x 10^4

= 0.59 X 10^10.

Therefore, we have;

5.9 X 10^9km.
