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)
