Lenny Conundrum - Round #

Habitarium Pest




Professor Clodbottle discovered a new breed of pest that seemed to divide itself into two in various lengths of time depending on its environment. He would say this discovery came after days of rigorous experimentation, but knowing him, it was probably on accident. Either way, this was quite astonishing! He'd never seen anything like it.



To experiment further and gather more data on the species, the professor created three separate Habitariums with various resources and space, but each starting with a single specimen at 10:00 NST.




  • Experimental Habitarium One resulted in the P3 dividing every 30 seconds. At exactly 11:03:30 NST (one hour, three minutes, and thirty seconds later) the Habitarium was half full.

  • Experimental Habitarium Two resulted in the P3 dividing every 45 seconds. At 11:49:15 NST (one hour, 49 minutes, and fifteen seconds later) the Habitiarium was half full.

  • Experimental Habitarium Three resulted in the P3 dividing every 60 seconds. At 12:13:00 NST (two hours, thirteen minutes later) the Habitarium was half full.



At what time would Experimental Habitarium Three be completely full?
