Answer:
The required equation is ![P(t) = -52t + 480](https://tex.z-dn.net/?f=P%28t%29%20%3D%20-52t%20%2B%20480)
Step-by-step explanation:
Consider the provided information.
Let P represent the number of pages left to read after t hours.
Shryia read a 480-page-long book cover to cover in a single session, at a constant rate. After reading for 1.5 hours, she had 402 pages left to read.
Total number of page Shryia read in 1.5 hours is:
480-402 = 78
It is given that the rate is constant i.e 1.5 hours,
Therefore, she read 78 pages in 1.5 hours.
She can read
page per hour
The required equation is:
![P(t) = -52t + 480](https://tex.z-dn.net/?f=P%28t%29%20%3D%20-52t%20%2B%20480)
Where t represents the number of hours.
