✔ 最佳答案
When the minute hand turn 360 degree, the hour hand turn (1/12)*360 = 30 degreeTherefore, the angle ratio for minute hand and hour hand = 360/30 = 12
Therefore, when hour hand turn x degree, minute hand turn 12x degree

時鐘由 12 → 1 → 2 → 3 ................ → 12 共有 12 格
時針 得了1格 例如 由 12 → 1，分針便行了 12 格了，所以 分針 比 時針 行快 12 倍。
