If a tank of water can provide 50 families with water for 5 days then that same tank could provide 20 families with 8 days of water.
Think of this question as a ratio. 50:5 (50 families to 5 days) Since this ratio simplifies to 10:1 that says that for every 10 families taken away you gain an additional day that the said tank of water lasts.
- 50 Families use a tank of water that lasts 5 days
- 40 Families use a tank of water that lasts 6 days
- 30 Families use a tank of water that lasts 7 days
- 20 Families use a tank of water that lasts 8 days.
