Understanding Naoya's Reading Journey

The video tutorial explains how Naoya reads a book at a rate of 55 pages per hour. After four hours, he has 330 pages left. The tutorial explores different methods to determine the total length of the book and the time it takes to finish reading. It uses a table to track reading progress and applies linear equations to solve the problem, demonstrating multiple approaches to reach the same solution.

What is the function that describes the pages left to read over time?

• L(t) = -55t + 550

• L(t) = 55t + 550

• L(t) = -55t - 550

• L(t) = 55t - 550
