The answer should be w = 3
3w = -24 + 33
3w = 9
w = 9/3
w = 3
As per the problem
The escalator make a 30° angle with the floor .
The escalator have a vertical height of 36 feet.
Now draw the diagram with the given information, the diagram is attached below
From the diagram,
Horizontal length=AB=d
Distance traveled by the person on the escalator stairs=AC=l
In triangle ABC,

Again in triangle ABC, Using Pythagoras Theorem

The horizontal length needed is 
The distance a person would travel on the escalator stairs is 72 ft
I would say 1257
I mate be wrong so I won’t go with my answer
The third option is correct.
