A cash register in a certain clothing store is the same distance from two dressing rooms in the store. If the distance between the two dressing rooms is 16 feet, which of the following could be the distance between the cash register and either dressing room?

I. 6 feet
II. 12 feet
III. 24 feet

答案是II 和III

雖然我選對了~可是還是有疑惑~請問最遠的距離可以到多少feet呢?
有上限嗎? 謝謝~~

最遠沒有上限, 像三角形的兩點固定, 第三點可無限延伸吧
但最短不可以低於16/2=8

了解了~~謝謝~~

不好意思，我不懂為什麼最短距離不
能低於 16/2=8 呢？ (汗顏...)

見圖檔..我想的太複雜了，只要看abc等腰三角形部分就可以了，不必管重心那部份
我一開始也跟你想的一樣，我也汗顏..
就算abc在一直線上，ab也會有8

真是厲害...突然覺得我真的
在準備AT嗎？ 怎麼腦筋很死...

which of the following could be the distance between the cash register and either dressing room?

請問這句話加了either 是什麼意思呢?
謝謝!!!
