The answer is 42 times
(41 times is not enough with 219,902 km)
How I derived my answer:
Used the following formula to find out how many of something you will have after doubling it N nbr of times
where s is the original size
s * 2^(n)
A standard sheet of paper is about 0.1 mm so 42 folds would give us this:
0.1 * 2^(42) = 439,804,651,110 mm
Rounded that's 440 billion millimeters, or 439,805 kilometers.
Too tired to try the bonus challenge before the time runs out. I might return!😀
