The number of weeks that it takes to empty the lake is; 350/11 weeks
<h3>How to solve fraction problems?</h3>
We are told that Officials begin to release water from a full man-made lake at a rate that would empty the lake in 14 weeks, but a river that can fill the lake in 25 weeks is replenishing the lake at the same time.
Let w = number of weeks required to empty the lake
let the completed job = 1 (an empty lake)
Thus;
w/14 - w/25 = 1
Multiply through by 350 to get;
25w - 14w = 350
11w = 350
w = 350/11 weeks
Thus, the number of weeks that it takes to empty the lake is; 350/11 weeks
