    1 corner will be 1/66 of 30 minutes

    30/1 x 1/66 = 30/66

    30/66 = 10/33 minutes

    = 0.455 minute

    0.455 x 60 = 27.3 seconds

    If you did 30 in 66 minutes, you do one in 30/66 minutes.  That's 0.455 minutes (rounded to 3 places).

    Now we don't usually say 0.455 minutes.  So you can convert that into seconds by multiplying it by 60.  0.455*60 = 27.24 seconds.
