To find the unit rate of pages read per minute, you can divide the total number of pages by the total time in minutes.
Anthony read 46 pages in 23 minutes.
The calculation would be:
\[ \text{Pages per minute} = \frac{46 \text{ pages}}{23 \text{ minutes}} = 2 \text{ pages per minute} \]
So, Anthony read 2 pages per minute.
