Final answer:
Mei read for a total of 1009 minutes over three weeks, which is more than the required 1000 minutes to win a book, so she did win a book.
Step-by-step explanation:
To determine if Mei won a book in the Read-a-Thon, we need to calculate the total number of minutes she read over the three weeks. Mei's reading times for the first, second, and third weeks were 328 minutes, 346 minutes, and 335 minutes, respectively.
- Add the number of minutes read in the first week: 328 minutes.
- Add the number of minutes read in the second week: 346 minutes.
- Add the number of minutes read in the third week: 335 minutes.
- Calculate the total minutes: 328 + 346 + 335 equals 1009 minutes.
Since Mei read a total of 1009 minutes, which is more than the required 1000 minutes to win a book, she did indeed win a book.
