The rate at which Sydney can read the pages of a certain book, article, or whatsoever write-up is given to be 50 pages per 40 minutes. This can be better expressed as,
                50 pages/40 minutes
The number of pages that she can read each minute is calculated by dividing both the numerator and the denominator of the ratio by 40, giving us,
                       (50/40) / (40 /40)
The new ratio is now 1.25:1

ANSWER: 1.25 pages per minute

Sydney can read 5/4 or 1.25 pages in one minute

Data;

  • number of pages = 50
  • time taken = 40 minute
  • rate = ?

What is Rate

This can be defined as the measure of one unit against another unit.

If it take Sydney 40 minutes to read 50 pages, let's calculate how many pages she will read in one minute to determine her rate.

[tex]40 pages = 50 minutes\\x pages = 1 minute[/tex]

Let's cross multiply both sides and solve for x

[tex]50 pages = 40 minute\\x pages = 1 minute\\x = \frac{50*1}{40}\\x = 1.25 page[/tex]

From the calculations above, Sydney can read 5/4 or 1.25 pages in one minute.
