Question

Last Monday, two law students met up at Café Literatura after school to read the pages they were assigned in the Legal Methods class. Alejandro can read 1 page per minute, and he has read 28 pages so far. Carly, who has a reading speed of 2 pages per minute, has read 12 pages so far. What is the rate of change for Alejandro?

a) 2
b) 12
c) 1
d) 28

Answer 1

The rate of change for Alejandro can be found by using the difference in the number of pages he has read over a specific time interval and dividing it by the change in time. In this case, the rate of change for Alejandro is 16/t pages per minute.

Step-by-step explanation:

The rate of change for Alejandro can be determined by finding the difference in the number of pages he has read over a specific time interval. We can use the formula:

Rate of change = (Change in pages read) / (Change in time)

Since Alejandro has read 28 pages so far and Carly has read 12 pages, the change in pages read for Alejandro is given by:

Change in pages read = 28 - 12 = 16 pages

Given that both students met up at Café Literatura after school, we can assume that they started reading at the same

time. Therefore, the change in time is the same for both students. Let's assume they read for t minutes.

Using the information given that Alejandro can read 1 page per minute, the rate of change for Alejandro is:

Rate of change = (16 pages) / (t minutes)

Therefore, the rate of change for Alejandro is (16/t) pages per minute.
