Seems that you're using a bad online translator...
1. The time taken for the stone to fall from the mouth of the well to the water inside is given by:
Where s = distance
u = initial speed
t = time
a = acceleration due to gravity
2. The time for the sound to reach your ears is given by:
whereis the time that the sound takes.
3. Since the distances are the same, equate the two equations. Also, you know that
That makes a quadratic equation. Solve for t and replace in one of your initial formulae to obtain the value of s, the distance.
