    Triangle Problem (Need help fast, please reply quickly)

    Three wooden equilateral triangles of side length 18 inches
    are placed on axles as shown in the diagram to the right. Each axle
    is 30 inches from the other two axles. A 144-inch leather band is
    wrapped around the wooden triangles, and a dot at the top corner is
    painted as shown. The three triangles are then rotated at the same
    speed and the band rotates without slipping or stretching. Compute
    the length of the path that the dot travels before it returns to its
    initial position at the top corner
