Lined up 6.7 billion people assume that each person occupied 12inches of the line.how many times around earth would they reach
If C is the circumference of the earth, in inches, then that would be
6.7*10^9 * 12 / C
So, look up C.
To calculate how many times around Earth 6.7 billion people lined up would reach, we can follow these steps:
1. Calculate the total length of the line:
Total Length = 6.7 billion people * 12 inches/person
2. Convert the total length to a unit that is more commonly used for measuring Earth's circumference. The most commonly used unit is kilometers. 1 inch is approximately equal to 0.0000254 kilometers.
Total Length (kilometers) = Total Length (inches) * 0.0000254 kilometers/inch
3. Finally, divide the total length (in kilometers) by the circumference of Earth to find out how many times around Earth they would reach.
Times around Earth = Total Length (kilometers) / Circumference of Earth
Now, let's calculate:
Circumference of Earth:
The circumference of Earth is approximately 40,075 kilometers.
Total Length:
Total Length = 6.7 billion * 12 inches = 80.4 billion inches
Converting Total Length to kilometers:
Total Length (kilometers) = 80.4 billion * 0.0000254 = 2,044,160 kilometers
Calculating Times around Earth:
Times around Earth = 2,044,160 kilometers / 40,075 kilometers ≈ 50.98
Therefore, if 6.7 billion people were lined up with each person occupying 12 inches of the line, they would reach around Earth approximately 50.98 times.
