To find out how many pages Sydney can read per minute, you can use the formula:

$\text{Pages per minute} = \frac{\text{Total pages}}{\text{Total time in minutes}}$

Given:

• Sydney reads 50 pages in 40 minutes.

$\text{Pages per minute} = \frac{50}{40} = 1.25 \text{ pages per minute}$

So, Sydney can read 1.25 pages per minute.
