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

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

Answer 2

Answer:
`1.83\text{ feet}`

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*5280=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 :-

`(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}`
