There is a minute hand and an hour hand. No second hand, here.

Since a new hour begins every 60 minutes, the minute hand travels 360 degrees per hour while the hour hand travels 30 degrees per hour. So when the minute hand moves x degrees, the hour hand is moving x/12 degrees.

emerald: if both hands are overlapping perfectly, would you be able to tell me which hand was the hour and minute hand? When would you be unable to tell?
