First, as Michael pointed out, you probably want to divide modulo 60,
and you want the minutes to be based on seconds_elapsed rather than
seconds.



Second, each time you % and / the same number by the
same integer, you might want to use Numeric#divmod instead:

def time_str secs
  secs.divmod(60).join ':'
end

(57..62).map { |secs| time_str secs }
# =3D> ["0:57", "0:58", "0:59", "1:0", "1:1", "1:2"]



Third, as Rick pointed out, if you prefer 1:02 to 1:2, you can do this:

def time_str secs
  '%d:%02d' % secs.divmod(60)
end

(57..62).map { |secs| time_str secs }
# =3D> ["0:57", "0:58", "0:59", "1:00", "1:01", "1:02"]



=E2=80=94 Shot (and, apparently, his ironic signature AI having a good day)
--=20
It=E2=80=99s great to be smart =E2=80=99cause then you know stuff.
