These lines are perpendicular!
y = x
y = -x–2
The slopes are reciprocals of each other, so they are perpendicular.
8/9 = 0,8
0,8/4 = 0,2
so each piece was 0,2 yard long
Sean read 15 of a book in = 112 hours,
so, 1 of a book in = 112/15
Now, 12 of a book would be: 112/15 * 12 = 112/5 * 4 = 89.6
89.6 = 89 6/10 = 89 3/5
In short, Your Answer would be 89 3/5 hours
Hope this helps!
