Plane drops package; superman on ground flys at angle then horizontal to meet package

Homework Statement



note:I am not 100% positive of the wording of this problem. As it stands, I am not looking to get help on plugging on equations and such. I am looking for help on how to draw the problem.

A cargo plane is flying horizontally at a velocity of V meters per second. and at a height of H meters. Superman is on the ground motionless. When the plane passes over him, a package drops from the cargo plane and superman first flies at an angle of 30 degrees and then horizontally to meet the package. What is the velocity of superman when he is flying horizontally?


Homework Equations





The Attempt at a Solution



Again, I am confused as to how to draw this out. It doesn't make sense. I don't think there is enough information. How am I supposed to know when he goes from 30 degrees to horizontal? If someone can sketch this out and make this clear, because it is not clear to me, I will do the rest and try to solve the problem.

Thank you.

How about this?

I agree that the information supplied is not enough to give more than a general answer.
I assume you have to give this horizontal speed vh in terms of V and H (obviously) and also in terms of the initial speed up to A (va) and the time for which he does this.
You may need to check the actual wording in the question.
As it stands he can meet the package anywhere between T and X depending on how he divides his time between the two stages, OA and AB.
A clue here is that the time taken for him to reach B is the same time as the package takes to fall vertically a height hb
