Interpreting scale drawings

The earth is approximately 80008000 miles in diameter. The moon is approximately 20002000 miles in diameter. The distance between the two is approximately 240,000240{,}000 miles.
You build a two-dimensional scale model of the earth and moon. You use a circle with a diameter of 11 inch to model the moon.
In your model, what is the diameter of the earth in inches?
  • Your answer should be
  • an integer, like 66
  • an exact decimal, like 0.750.75
  • a simplified proper fraction, like 3/53/5
  • a simplified improper fraction, like 7/47/4
  • a mixed number, like 1 3/41\ 3/4
inches
