Fluid Dynamics Question(not too difficult)

Homework Statement

The spout heights for a container are 10 cm, 20cm, 30cm, and 40cm. The water level is maintained at a 45 cm height by an outside supply. Which water steam has the greatest range relative to the base of the container.
---
I know that the one at 20cm is the greatest range already. I want to find out the actual range though.

Homework Equations

V=radical(2gh)

The Attempt at a Solution

For 20 cm: V=radical(2gh)
V=radical(2*9.81*.25m)
V=2.215m/s
So I have the velocity but I am confused about how to find the range. Which formula do I use and what values go where?

Do I use: Vfinal^2 - Vinitial^2=2aS, with S being distance
OR
Sfinal=1/2aT^2+ViT+Si with T=time and S=distance

UPDATE: Figured out the answer to my question, thanks :)
