7.If Ruth began a job and worked continuously until she finished, at what time of day did she finish the job?
(1)She started the job at 8:15 a.m. and at noon of the same day she had worked exactly half the time that it took her to do the whole job.
(2)She was finished exactly 7 1/2 hours after she had started.
Ans:A
我選C,如果答案真的是A的話,是不是因為那個“noon”就代表著正午12點整,否則真想不透為何要選A? 謝謝解答唷^^
