Course authors can add in reading times so learners can quickly see how long they may need to spend reading each page.
How to set the reading time for a page
Head to a page within a course you are editing.
Then use either:
Page settings in the header, or
The Pencil next to the page title.
Both options open Page settings where you can type or use the up/down arrows to edit the Reading time.
Scroll to the bottom to Save.
