How much broadcast time did it take for Planet Namek to blow up? In Dragon Ball Z, during Goku's fight with Frieza, Frieza decides to destroy the planet Namek. However he fails to do so, but he claims that the planet will blow up in 5 minutes, at the most, but several episodes later, the two are still seen fighting. 

Exactly how much broadcast time (real time) elapsed before the planet actually blew up? 

I am looking for the total broadcast time (NOT the time passed in-universe) it took for planet Namek to explode. 

Excluding: 


OP and ED theme time 
Commercials
Events happening concurrently with the Frieza battle


But including: 


Fillers (the concurrent event rule applies here as well)


Starting from: 


When Frieza says that it will take five minutes 


Ending when: 


The planet actually blows up
Interestingly enough, the TVTropes link I linked in the comments had the answer


  Taken to insanity during Goku's fight with Freeza. Freeza destroys the
  core and gives the planet five minutes until implosion. Ten episodes
  (approximately three hours of screentime for each of the scenes that
  are playing out simultaneously) and over three hundred lines of dialog
  for the two fighters later the planet finally collapses.


So there you go.  


10 episodes
3 hours (roughly)
100 lines of dialog


although, apparently it was


  Lampshaded snarkily in the dub. With ten episodes to go, Frieza has a
  line to the effect that the planet is "a tough one... it'll probably
  last another two minutes."
