Given the rationale, provide a reasonable question and answer. Step-by-step reasoning process: First find the total number of days in 6 weeks: 6 weeks * 7 days / week = 42 days. Then find the total difference in the number of pages Janet and Belinda read each day: 80 pages / day - 30 pages / day = 50 pages / day. Then multiply the daily difference by the number of days to find the total difference in the number of pages they read: 50 pages / day * 42 days = 2100 pages.
 The question and answer:
If Janet reads 80 pages a day and Belinda reads 30 pages a day, how many more pages does Janet read in 6 weeks?
The answer is 2100
