An archer shoots and arrow horizontally at a target 15m away. The arrow is aimed directly at the center of the target, but it hits 52 cm lower. What was the initial speed of the arrow?

I know it has something to do with a zero launch angle but none of the equations i use come out to the correct answer in the back of the text.

How far did it fall? ANS .52 cm
How long did it take to fall? ANS d=1/2 g t^2 solve for t.
What was the speed of arrow? 15/t
