Question 987081: The distance around the world is approximately 40,000 km. Approximately how many people of average size would it take to stretch around the world if they were holding hands?

You can put this solution on YOUR website! The average wingspan is about 1.5 meters (of course some wingspans are shorter or longer, it depends on a number of factors).
40,000 km = (40,000 km)*(1000 m/1km) = 40,000,000 meters
--------------------------------------------------------------------
Divide the total distance (40,000,000 meters) by the length of the average wingspan (1.5 meters)
40,000,000/1.5 = 26,666,666.6666667
Round to the nearest whole number to get 26,666,667
You would need approximately 26,666,667 people (if you round to the nearest million, about 27 million people)
