The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

Subpart 1: Answer to Questions 4 and 5<\/strong><\/p>\n\n\n\n

4. Time to reach Pluto<\/strong>
At a speed of 25,054 miles per hour, it would take approximately 14.89 years<\/strong> to travel the average distance of 3.27 billion miles to Pluto.<\/p>\n\n\n\n

Now, I’ll calculate the number of dollar bills that could fit in the Apollo astronauts’ living quarters.<\/p>\n\n\n\n

5. Number of Dollar Bills in Apollo Astronauts’ Quarters<\/strong>
The Apollo astronauts’ living quarters (213 cubic feet) could fit approximately 5,341,288<\/strong> dollar bills.<\/p>\n\n\n\n

Now, I’ll move on to Subpart 2, calculating the stack height of dollar bills in the amount of U.S. national debt.<\/p>\n\n\n\n

Subpart 2: Answer to Questions 6 and 7<\/strong><\/p>\n\n\n\n

6. Height of a Stack of Dollar Bills Representing the U.S. National Debt (2021)<\/strong>
If all 28.7 trillion dollar bills were stacked flat, the stack would reach approximately 1,947,759 miles<\/strong> high.<\/p>\n\n\n\n

Now, I’ll check if the stack of dollar bills for the U.S. national debt (2020) would reach from Earth to the Moon.<\/p>\n\n\n\n

7. Would the 2020 U.S. National Debt Stack Reach the Moon?<\/strong>
The total height of a stack of dollar bills for the 2020 U.S. national debt (26.7 trillion dollars) would be 1,812,027 miles<\/strong>, which is much greater<\/strong> than the average Earth-to-Moon distance of 238,855 miles<\/strong>.
So, yes, the stack would reach far beyond the Moon!<\/p>\n\n\n\n

Now, I’ll move to Subpart 3, calculating the percent error in Pluto’s diameter measurement and checking the weight of a person on the Moon and Pluto.<\/p>\n\n\n\n

Subpart 3: Answer to Questions 8 and 9<\/strong><\/p>\n\n\n\n

8. Percent Error in Pluto\u2019s Diameter Measurement (2007 vs. 2015)<\/strong>
The percent error in the 2007 measurement of Pluto\u2019s diameter was -2.11%<\/strong>. The negative value indicates that the 2007 measurement underestimated Pluto\u2019s actual diameter.<\/p>\n\n\n\n

Now, I’ll determine the correct weight of a 140 lb person on the Moon and Pluto.<\/p>\n\n\n\n
