Answer: It will take about 19 hours to read the book.
Step-by-step explanation:
Given: Rate of reading = 1.26 pages per minute
Total pages = 911 pages
Time taken to read = (Rate of reading ) x (Total pages to read)
= 1.26 x 911 minutes
= 1147.86 minutes
hours [ 1 hour = 60 minutes]
= 19.131 hours
hence, it will take about 19 hours to read the book.
The number is 5.
3x=5+2x
