Question

jolie can read around 14 sentences per minute of her current novel. She wants to finish reading her book before the movie comes out next week. If she has 17 pages left to read and each page has about 120 sentences , how many hours should jolie sit aside to complete her reading?

Answer 1

Start at the beginning. 17 pages times 120 sentences is the first thing.
17 x 120 = 2040. So she has to read 2,040 sentences. If we now divide 2.040 by 14 pages/minute, we shoud get

2,040 divided by 14 = 145.7

The last thing to do, is changes those minutes into hours by dividing by 60.
2.42 hours.
