Find Justine’s reading rate
Rate = Pages / Time = 85 pages / 45 minutes = 1.89 pages per minute
Find Cara’s reading rate
Rate = Pages / Time = 60 pages / 35 minutes = 1.71 pages per minute
Compare rates
Justine: ~1.89 pages/min
Cara: ~1.71 pages/min
Conclusion
Justine read faster because she read more pages per minute than Cara.

Find the total number of books
Each carton has 20 books, and there are 120 cartons:
120 × 20 = 2,400 books total
Find how many are math books (10%)
10% of 2,400 = 0.10 × 2,400 = 240 math books
Subtract math books from total
2,400 - 240 = 2,160 books that are not math books
Correct answer: 2,160
