1 billion around earth

  1. 1. Did you know……..<br />If you took 1 billion people standing side by side- shoulder to shoulder, they would be able to go around the earth’s circumference 12 ½ times!<br />
  2. 2. We measured 3 people and found that the distance end to end was about 59 inches.<br />Using proportions 3 𝑝𝑒𝑜𝑝𝑙𝑒59 𝑖𝑛𝑐h𝑒𝑠=1,000,000,000 𝑝𝑒𝑜𝑝𝑙𝑒𝑥 𝑖𝑛𝑐h𝑒𝑠<br />Solving by using cross-multiplication 1 billion people would be 19,666,666,666 inches<br />Since 1 ft is 12 inches then 19,666,666,666 𝑖𝑛𝑐h𝑒𝑠12 𝑖𝑛𝑐h𝑒𝑠 = 1,638,888,888 ft.<br />The internet said the circumference of the earth is about 131,479,713.54 ft.<br />This means that 1,638,888,888 𝑓𝑡131,479,713 𝑓𝑡 = 12.5 times around the earth for 1 billion people<br /> <br />
