Let the speed off the walk way be x and speed of the walkway be y
x+y=6....i
x-y=2....ii
adding the above equation we get:
2x=8
thus
x=4 ft/s
and
y=6-4=2 ft/s
thus the speed off the walk way is 4 ft/s
the speed of the moving walkway is 2 ft/s

x = 300
Answer:
A) y = 4
Step-by-step explanation:
Line AB is a vertical line, so a line perpendicular to it would have to be a horizontal line (perpendicular lines make an "x" shape with one another). Horizontal lines are written as y = ___ .
The perpendicular line also has to pass through the point (2,4). Points are written as (x, y). Therefore, the y-value in (2,4) is 4.
The perpendicular line has to be y=4 since it passes through both the Line AB and the given point.
