Answer:

$-2\dfrac{1}{4}\div\left(-\dfrac{2}{3}\right)=\dfrac{27}{8}=3\dfrac{3}{8}}$

Step-by-step explanation:

If a line of one billion people stretched 327,495 miles long, the average shoulder width of the people in the line is A feet. Ro

Ganezh [65]

Answer:

1.7 ft

Step-by-step explanation:

We presume you want to find A. And we presume the people are standing shoulder-to-shoulder.

(327,495 mi)/(10^9 persons) = (3.27495×10^5 mi)/(10^9 persons) × (5280 ft/mi)

= 1.7291736×10^9 ft/(10^9 persons)

= 1.7292736 ft/person

≈ 1.7 ft/person
