A circular gear with a diameter of 25 cm is mounted directly over another circular gear with a diameter of 100 cm. Both gears run on the same axle at their exact centers and each gear has a single notch at the 12 o'clock position. At the same moment, the gears start to rotate at the same rate in cm/s, with the larger gear moving clockwise and the smaller gear moving anticlockwise. How far in centimeters will the notch on the larger gear have moved the second time the notches pass each other?
