Leilani can read 20 pages in 2 minutes. if she can maintain this page, how many pages can she read in an hour?
We know that 1 hour is 60 minutes.
Let p be the number of pages Leilani can read in 1 hour (60 minutes)
The read rate is constant, so we can build a proportion.
20 pages /2 minutes = p/60
We can cross multiply:
Numerator 1 * Denominator 2 = Denominator 1 * Numerator 2
Solving for Numerator 2 we get:
Numerator 2 = Numerator 1 * Denominator 2/Denominator 1
Evaluating and simplifying using your input values we get:
p = 20 * 60/ 2
p = 1200/2
p = 600
