    Some would argue it should be the entire hour-and-twelve-minute lecture. – WS2 Sep 15 '16 at 07:36
  • Hour and twelve minutes (and its hyphenated equivalent hour-and-twelve-minute [lecture]) is awkward; why not replace it by seventy-two-minute lecture ? – David Handelman Sep 15 '16 at 14:45

Hour-and-twelve-minute is an adjectival phrase describing 'lecture'.

It is simpler for a reader to see this if the words are hyphenated.

"...during the entire hour and twelve minutes lecture.", is the better one,

The dash is a handy device, informal and essentially playful, telling you that you're about to take off on a different tack but still in some way connected with the present course — only you have to remember that the dash is there, and either put a second dash at the end of the notion to let the reader know that he's back on course, or else end the sentence, as here, with a period. __ Lewis Thomas
