(The first page is the beginning of the equation, and the next page is the ending)
Since both of them are 3 meters from one side of the 25 meter pool, the distance that they have to cover is actually only 22 meters only. To answer this item, we let x be the distance covered by Ario and 22-x be his remaining distance. Such that,
x/(22-x) = 1/4
The value of x from the equation is 4.4.
Therefore, the distance that Ario had covered is 4.4 m.
