A circle rolls on the onside of the circumference of a round clock in a 2-dimensional plane, they touch only at one point. The circle has an arrow pointing straight up when it's initially placed at the number 12 on the clock. The circle starts to roll clockwise along the circumference of the clock, and the arrow rotates as it rolls. Where is the circle (at what number on the clock) when the arrow first point straight up again?
