Free Fall Problems (Urgent)

I'm working on a homework and I've found there's a problem I can't find a solution to:

A boy throws rocks up to a height we will name "H". How far must he throw the rocks for them to be twice the time in the air.

-At first, the problem seems easy, as it is obvious that if it takes a certain time to throw them to a certain distance, twice that time will make exactly twice that distance (If t*2=2t, and if H is directly related to t, then 2t=2H). After doing this I thought it might not be that simple, as I can't assume that the time is equivalent to the height if the problem does not say so expressely. So I thought I'd ask if it really is that simple, and if not, can you point me in the right direction? I've been cracking my brain for about 5 days and I can't find a solution.

Thanks a lot in advance
