The page count will be 10 when the two students will reach the same count.
Step-by-step explanation:
Given,
Typing speed of Annie = 3 pages per hour
Pages already typed by Annie = 4
Let,
x be the number of hours.
y be the total pages typed.
y = 3x+4 Eqn 1
Typing speed of Whitney = 1 page per hour
Pages already types by Whitney = 8
y = 1x+8 Eqn 2
For same number of pages;
Eqn 1 = Eqn 2
Dividing both sides by 2
Putting x=2 in Eqn 1
Putting x=2 in Eqn 2
The page count will be 10 when the two students will reach the same count.
