Answer:
The correct answer is 0.0667 centimeters.

Diameter of earth is 12700 kilometers.
Width of the solidified ocean crust is 35 kilometers.
Ratio between the diameter of the earth and the solidified crust is .
Now the earth is shrunken to a size of a basketball with the diameter as 24.2 centimeters. Let the thickness of the Earth's crust in this model be x centimeters.
Ratio between the diameter of the model earth and the solidified crust is .
But this ratio of the real Earth and its model must be equal.
∴ =
⇒ x = 0.0667 centimeters.
