Question

It took Mariah 3 hours to read 120 pages. How many pages can she read in 1 hour at the same rate?

Answer 1

Mariah can read 40 pages in 1 hour at the same rate.

Step-by-step explanation:

Let's determine how many pages Mariah can read in 1 hour at the same rate.

We know that Mariah can read 120 pages in 3 hours, so we can set up a proportion:

3 hours / 120 pages = 1 hour / x pages

To solve for x, we can cross multiply:

3x = 120 * 1

3x = 120

x = 120 / 3

x = 40

Therefore, Mariah can read 40 pages in 1 hour at the same rate.
