An air traffic controller works 4 consecutive days and then has 4 consecutive days off. If the first day that she worked was a Monday and she is working 34 days later, which day of the week will she next have off?

(A) Monday
(B) Tuesday
(C) Wednesday
(D) Friday
(E) Sunday

正確答案 (B)

請問she is working 34 days later 這句話是說之後她連續工作34天嗎？ 我題目看不太懂..而且也不知道怎麼算
誰可以救救我...

"she is working 34 days later" 這句話的意思是說她已經工作了34天...(而非上34天的班...)
如果以"4天上班 + 4天休假"看作一個單位的話
則　34 / (4+4) = 4 ... 2 （已輪過4輪且又多工作2天)
所以需要再工作2天才能休假（也就是說第37天可以休假）
又　34 / 7 = 4 ... 6 （第34天是星期六)
所以下一次休假日從星期二開始　故選B
