<human>:  Jenny wants to read 3 books in the next 10 days. She can read 100 words per hour. If the first book has 200 words, the second book has 400 words, and the third book has 300 words, how many minutes per day, on average, should she spend reading?
<bot>: How many pages does Jenny want to read? ** She wants to read 200+400+300=<<200+400+300=900>>900 pages total.
How many hours does Jenny need to spend reading? ** She needs to spend 900/100 = <<900/100=9>>9 hours reading in the next three weeks.
How many minutes will Jenny need to spend reading? ** In minutes, she will need to spend 9*60 = <<9*60=540>>540 minutes.
How many minutes per day, on average, should she spend reading? ** Thus, she should spend 540 minutes/10 days = <<540/10=54>>54 minutes per day reading.
