Area of one rectangle: l × w
7 × 4 = 28

So, 14 sentences per minute = 840 sentences per hour (60 minutes in an hour, 14(60)=840)
If 17 pages have 120 sentences on each page, we can conclude that there are a total of 2040 sentences that remain (17x120=2040)
If Jolie can read 840 sentences per hour, we can divide 2040/840 (total # of sentences left divided by sentences per hour)
2040/840 = 2.43 hours.
