Not enough information. Median wait time is worthless here if you are looking for mean wait time.

Actually, upon reflection, there may be enough information IF you make a bunch of assumptions. This is basically a queuing theory problem, and if you assume the arival and service distributions, and those distributions are easy to work with (like the standard distributions you use in queue theory), and maybe make some more assumptions, then you may be able to calculate this, but that is a lot of assumptions to make and I am too lazy to refamiliarize myself with queue theory right now.
