Question

Dropping less than two inches per mile after emerging from the​ mountains, a river drains into the ocean. One​ day's discharge at its​ mouth, 2 trillion​ gallons, could supply all of country​ A's households for five months.Based on this​ statement, determine how much water an average household uses each month. Assume that there are 100 million households in country A.

Answer 1

4000 gallons.

Explanation:

One day's discharge at the mouth of the river is 2 trillion gallons and it can supply all of country A's households for five months.

Now, if there are 100 million households in country A.

Then, the amount of water an average household uses each month will be given by

`(2 * 10^(12) )/(100 * 10^(6) * 5) = 4000` gallons. (Answer)
