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

Answer: $1.83\text{ feet}$

Step-by-step explanation:

Given : If a line of one billion people standing shoulder to shoulder stretches 346,439 miles long.

We know that 1 mile =5280 feet

Then, the length of line=$346439\times5280=1829197920$ feet

We know that 1 billion can be written as :

$1,000,000,000=10^9$

Now, the average shoulder width of the people in the line :-

$\dfrac{1829197920}{1000000000}=1.8291979\approx1.83\text{ feet}$

Hence, the average shoulder width of the people in the line is about $1.83\text{ feet}$

Answer 2

The answer in scientific form is 1.829198 • 10^9 but not in scientific form would just be 346,439 times 5280
