If I may indulge in a little reverse calculation:  In 16mm you've got
40 frames per foot of film.  One minute of film, at 24 fps, takes up
1,440 frames.  Divide that by 40 and you've got your answer:
36 feet per minute!
(Or, from another perspective:  a standard 100-foot roll runs 167
seconds; a 400-foot roll runs 667 seconds.)
I've never worked in 35mm, but I'd guess that it's twice as much since
the frames are twice as big--which would mean 72 feet per minute.
