Physics... math problem

Hello. I've got the following problem but I do not know if it
solvable... I've been trying os far many methods, but still I cannot
get it.
Check is out:
In a golf camp a hole is at 240ft horizonatlly and 64ft vertically. The
ball hits the hole 4 seconds after it was hit.
Get the magnitude and direction of the ball... Hence, get the Vo and
the angle.
+ We cannot divide the time between 2 to know the maximun height
because the altitude where you hit the ball is cero and the altitude of
the hole is 64ft.
+ We cannot divide the distance in X either to get the highest point.
Hence we cannot get the Vo of y neverthelles for X, Vo=64ft/s
I've though to make this a parabola in the analytical geometry way...
But we cannot get any info because the vertex, is unknown... (x,y) and
therefore we cannot know the x-intercepts.
I've tryed to do a relation, but I don't know if it will work...
Since x=240 when y=64, when when y=0, x is?
But the answer will be zero! And that cannot be that way! X keeps on
growing forever while x is positive in a part and negative in the
other...
So... I think this problem is impossible to solve.
If anyone has the answer or a key to get to it, that will be very
helpfull.
Maybe you think I am a little naive with this stupid high school
problems, :P But it's kinda hard for me since I'm only about to enter
high school and I've never seen this themes. I'm studying with books,
so any help from you will really help me get more knowledge. Thank you
once again!
