Answer:

3.2 miles

Explanation:

If the Astronomical units is about 1 A.U which is = 1/2 plate then the diameter = 2 inches will be of 10,000 AU 2 X 10,000 = 20,000 inches.

Thus the 20,000 A.U / 12 = 1,666 feet 1,666 / 5280 = /3 of a mile then the 10,000 AU 2 X 100,000 = 200,000 inches.

20,000 / 12 = 16,666 feet

16,666 / 5280 = 3.2 miles
