Target 3F: Identify and compare rates of change
Graduation Rate The graduation ceremony at Central High School began at 6:00 pm. Speeches were given by both students and administrators. Two students alternated reading names of the graduates alphabetically by last name as the graduates accepted their diplomas from the principal. ** Student A **, shown in ** blue **, began reading names, followed by ** Student B **, shown in ** red ** below. The two students continued to alternate reading their respective number names for all 227 names of the graduating class. 1. What is the name reading rate of change for ** Student A ** ?

2. What is the name reading rate of change for ** Student B **?

3. Estimate when the graduation will end if the pattern of ** Student A ** and ** Student B ** continue alternating reading the same number of names at the same rate.

4. Estimate how long the speeches took. How do you know?
