Assuming the average adult person is about 5.5 feet tall --
1 mile = 5,280 feet
25,000 * 5,280 = 132,000,000 feet
132,000,000 / 5.5 = 24,000,000
1 mile = 5,280 feet
25,000 * 5,280 = 132,000,000 feet
132,000,000 / 5.5 = 24,000,000
The average person lying head-to-toe takes up about 6 feet, which is equivalent to 0.001136 miles. So, to stretch around the Earth's roughly 25,000-mile circumference, we'll need approximately 25,000,000 people lying head-to-toe.
That means the answer is b) 25 million, and no, I promise I didn't have any clowns helping me with the math!
Now, we need to find out how many times the height of a person goes into the circumference of the Earth. The formula to calculate the number of people lying head-to-toe is:
Number of people = (Circumference of the Earth) / (Average height)
Given that the distance around the Earth is approximately 25,000 miles, we need to convert it into inches since the average height is in inches.
1 mile is equal to 5,280 feet, and 1 foot is equal to 12 inches. So, 1 mile is equal to 5,280 * 12 = 63,360 inches.
Now, let's calculate the circumference of the Earth in inches:
Circumference of the Earth = 25,000 miles * 63,360 inches/mile
Circumference of the Earth ≈ 1,584,000,000 inches
Finally, we can calculate the number of people lying head-to-toe:
Number of people ≈ (1,584,000,000 inches) / (60 inches)
Number of people ≈ 26,400,000
Therefore, the closest estimate to the number of people lying head-to-toe needed to stretch around the Earth is b) 25 million.
