Answer:
The required equation is [tex]P(t) = -52t + 480[/tex]
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 [tex]\frac{78}{1.5} = 52[/tex] page per hour
The required equation is:
[tex]P(t) = -52t + 480[/tex]
Where t represents the number of hours.
