第一題 If the rectangular plate can hold 3 cubic feet,then Col A:The number of cubic yards that 100 such plates can hold Col B:13 這題不是很懂題目在說什麼!! 第二題 Given three persons X,Y and Z working together,takes 9 hours to complete a work.If "Y" and "Z" working together takes 12hrs to finish the same job,then how much time would "X" take to finish the same job alone? 這題答案好像是36hrs，但想不太出來為什麼!!! 煩請大家幫幫忙，謝謝!! ^^ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 59.121.38.54
