Step-by-step explanation:
I did it on Khan
The required pages left are 20 pages after 5 hours.
Given that,
Nayeli is proofreading a 75-page manuscript. Filémon is line editing a 40-page manuscript. Since proofreading is faster, Nayeli completes 11 pages an hour, but Filémon only completes 4 pages an hour. When Nayeli and Filémon have the same number of pages left, how many pages will that be is to be determined.
What is arithmetic?
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
According to the question,
Let the time be x,
75 - 11x = 40 - 4x
35 = 7x
x = 5
Now,
Number of pages = 40 - 4x = 40 - 20 = 20
Thus, the required pages left are 20 pages after 5 hours.
