Answer:
2
Explanation:
To find the solution we must first make the transformations to international units,
In this way:
Inches of length (L) to feet =
So we can identify the area by hour:
Once the area is identified, we now identify the number of passes required,
Passes required = Area x number of passes
We transform speed to international units
So we can identify the covered area
where
<em>m = drum widht</em>
<em>p = efficiency</em>
In this way we obtain the number of rollers given by:
No. of Rollers = Passes required / covered area
No of rollers = 48136/40269
No of rollers = 1.19, that is, 2.
Number of rollers required are 2.
