Question

If a line of one billion people standing shoulder to shoulder stretches 346,439 miles long, what is the average shoulder width, in feet, of the people in the line?

Answer 1

Let us first convert the length from miles to feet. 1 mile = 5280 ft

length = 346,439 mile * (5280 ft / 1 mile)

length = 1,829,197,920 ft

 

So the average shoulder width is simply the quotient of the length and number of people, that is:

average shoulder width = 1,829,197,920 ft / 1,000,000,000 people

average shoulder width = 1.83 ft
