Answer:
y = -52x + 480
Step-by-step explanation:
Let us assume the number of pages left be x
And, the number of hours is x
According to the question
Data given is as follows
Number of hours 1.5 and 5
Total pages 480
Left pages 402
Based on the above information,
The computation is shown below;
Pages read by Shriya in 1.5 hours is
= Total pages in the book - left pages to read
= 480 pages - 402 pages
= 78 pages
And, there is 1.5 hours
So in one hour she read
= 78 pages ÷ 1.5 hours
= 52 pages per hour
So, the equation is
y = -52x + 480
