seconds?

110 meters is the distance where they will intersect

Explanation:

given,

liquid density = 1900 kg/m³

distance of upper hole = 19 m

distance of lower hole = 117 m

acceleration due to gravity  = 9.8 m/s²

the speed at each point

for upper hole    

                         v  = 19.29 m/s

lower hole      

                          v = 47.88 m/s

The path for each is parabolic

x = v t

we get

upper hole

 lower hole

 y for upper hole = 80 + y for lower hole

x = 109.32 meters

110 meters is the distance where they will intersect
