Mga sagot sa #1 sa Tanong: two hoses when connected to a swimming pool can fill together in four hours. if the larger hose alone is used, it can fill the pool in 6 hours less than the smaller hose. how long will it the smaller hose to fill the swimming pool alone?– ^-^

We let the time taken when ….
the larger hose alone is used be x – 6
and the smaller hose as x.

This would make their rates [tex] frac{1}{x-6} [/tex] and [tex] frac{1}{x} [/tex] respectively.

Take note that:
1 / rate = time 
so,
1 / rate of both hoses = 4
rate of both hoses = 1/4

[tex] frac{1}{x-6} + frac{1}{x} = frac{1}{4}\ frac{2x-6}{x^2-6x} = frac{1}{4} \ 8x-24=x^2-6x \ 0=x^2-14x+24 \ 0=(x-12)(x-2)[/tex]

This would mean that x = 12 or 2 but x cannot be 2 since that would make the time taken for the larger hose negative.

Therefore it will take the smaller hose 12 hours to fill the swimming pool alone.
