You photoread books at about one page per second.
Activation takes as long as you need to get the information that you want from a book. Books ouside you experience or knowledge area will naturally take more time than a field that you already know very well.
With photoreading you will finish the book in 1/3 to 1/5 or even 1/10 the time it take you to finish it now.
The time it takes to walk a mile depends on the layout of the land. If there is a well worn path it will take less time than if the terrain is rough. You'll find that a good reader will take that into consideration when they activate a book. It depends on what you want/need to know and the amount of time you have available.
