The neighbor's bubbling spring fills its clear water

We three Eroses fill - see - this basin.

I with my wings. This one with a jug. The other, through the tip of the arrow.

"The sun needs no more than a sixth,

To fill me - spoke - with a gentle murmur the winged one."

"I need four hours and I will fill this jug"

"I can fill this basin from my arrow in half a day"

Then spoke the Jug, - and the Archer as well

"If we all fill it at once - said the friend -

How long will it take for the basin to be full?"
Denoting the questioned time by $x$ and the volume of the bathtub by $V$, we obtain the following equation:

$$
x \frac{V}{4}+x \frac{V}{4}+x \frac{V}{12}=V
$$

from which

$$
x=1 \frac{5}{7} \text { hours. }
$$

Number of solutions: 31.
