Question

1. liam tracks the number of pages, p, he can read in a given number of hours, h, and records the data in the table below:

h	1	2	3	4	5
p(h)	25	50	75	100	125

select the number of pages per hour that liam reads.
75 pages per hour
125 pages per hour
25 pages per hour
50 pages per hour

Explanation:

Step1: Recall rate - formula

The rate of pages per hour is $\frac{\text{number of pages}}{\text{number of hours}}$.

Step2: Select a data - point

Let's take the first data - point where $h = 1$ hour and $p(1)=25$ pages.

Step3: Calculate the rate

The rate $r=\frac{p(1)}{1}=\frac{25}{1} = 25$ pages per hour. We can check other data - points as well. For $h = 2$ and $p(2)=50$, $r=\frac{50}{2}=25$ pages per hour. For $h = 3$ and $p(3)=75$, $r = \frac{75}{3}=25$ pages per hour, and so on.

Answer:

25 pages per hour
