A soccer ball is constructed using 32 regular polygons with equal side lengths. Twelve of the polygons are pentagons, and the rest are hexagons. A seam is sewn wherever two edges meet. What is the number of seams between a pentagon and a hexagon in the soccer ball?

Each side of a pentagon is sewn to a edge of a hexagon

5 x 12 = 60
