To find out how many pages Lizbeth read in one minute, we need to divide the total number of pages (50) by the total time it took her to read (75 minutes).
The formula to calculate the number of pages read per minute is:
Pages per minute = Total pages / Total time
Substituting the values, we have:
Pages per minute = 50 pages / 75 minutes
Calculating this, we get:
Pages per minute = 0.67 pages/minute
Therefore, Lizbeth read approximately 0.67 pages in one minute.
So the correct answer is: 0.67 pages/minute
