Sagot :
Answer:
24 days
Explanation:
for Mr.Adams
12 days ---> 1 barrel of water
1 days ---> 1/12 barrel of water
8 days ---> [(1/12)*8] = 8/12 barrel of water
For Mrs Adams in 8 days:
she uses: 1 - 8/12 = 4/12
If she camps alone:
she uses 4/12 in 8 days
to use full:
(4/12)*3 barrels in (8*3) days
1 barrels in 24 days
She can therefore use 24 days if she camps alone.
Mrs. Adams will use the water for 24 days.
Data;
- Mr. Adams = 12 days
- Mr. Adam + Mrs. Adam = 8 days
Fractions
