I think it's C. Responsibility
Please correct me if I'm wrong!! :) I'd be happy to fix it!!
First of all, find how many sentences are in 17 pages. If in one page there are 120 sentences, in 17...
17*120 = 2040 sentences.
Now, she can read 14 sentences in one minute, how many minutes to read 2040 sentences?
2040 : 14 = 145,71 minutes (about 146 mins).
So, in an hour there are 60 minutes
146 : 60 = 2,42 hours (about 2,5)
But you can also convert 145,71 mins = 2 hours and 25 mins.
You would add another ''p'' so it would be dropped
