a/h

You should apply Bernoulli's Theorem here using all the necessary assumptions like if the area of the surface of water is very large in comparison to the area of the hole, then by continuity equation you can easily neglect the velocity of the surface of the water. 
 After you get the velocity of the water coming from the hole, you need to find the range. You can find range by multiplying the velocity and time. Time can be found by using simple kinematic equation as height from the surface of water is given.

Give the problem a shot now. Post a comment for any queries. :)
