Can you split some of those tasks so that some are done at night before she can read her book in bed? Cleaning her floor and putting away clothes isn't a morning task if she sets out the day's clothes the night before and puts away everything else. No morning changes of mind. Same with packing her backpack or whatever she's going to need for the day. When that's done, she can read in bed. If she dawdles, she loses reading time.
When she gets up in the morning, she just has to put on what's been set out and she puts her book by the door with her backpack and shoes. She can brush her hair, eat breakfast and clean up her dish. When that is done, she can sit somewhere near the door (anyplace comfortable but not up in her room where you have to chase her down) and read to her heart's content.
