let A =(440,000/3.8 X 10^9) is how much in km each person would get.
If you want to show this as a percentage take (A/440,000) X 100.
I presume you meant ^9 and not *9
i haven't done maths for years, and now i'm face with it again at uni.
1) The shorelines of the earth (including lakes and the arctic and antarctic regions) total about 440 000km in length over ten times the earth's perimeter. If everyone of the world population (3.8 x 10*9 in 1974) decided to possess a portion of this shoreline, how much would he have on the average?
km. of shoreline.
This is approximately % of shoreline available for each person.
Check that arithmetic, though. That's a ridiculously small percentage.
One kilometer = 3, 280.8399 feet.
Each person would get about feet or inches of shoreline for their very own.
