Meh, I give it a C-
360° ÷ 60 sec = 6°/sec
If we're lining up the Q clock with the unit circle:
-30° is 120° from where 12 would be on the clock, ergo 120° ÷ 6°/sec = 20 sec (on the Q clock)
-30° = 330° = 20 secs on Q clock
-45° = 315° = 22.5 secs on Q clock (makes little sense, maybe round to 23)
-60° = 300° = 25 secs on Q clcok
-90° = 270° = 30 secs on Q clock
