I'm struggling, please help.
Thank you in advance. Answer by longjonsilver(2297) (Show Source):
You can put this solution on YOUR website! 1 person = 8.79x10^5 litres of water
2 people = 2x 8.79x10^5 litres of water
3 people = 3x 8.79x10^5 litres of water
4 people = 4x 8.79x10^5 litres of water
6x10^9 people = 6x10^9x 8.79x10^5 litres of water
--> 5.274x10^15 litres of water.
--> when stuck, start with an easy example and then spot the pattern.
