Since the carpeting has a width of 10 feet, 1 square foot of this carpet has length 1/10 of a foot. Recall that 1 hour is 3600 seconds. To find how long it takes 1 square foot of this carpet to move through the dryer, we can let t be the time in seconds that it takes 1/10 of a foot to move through. We’ll then form the following proportion: 2160 feet is to 3600 seconds as 1/10 of a foot is to t seconds.

2160/3600 = (1/10)/t

t = /2160

t = 360/2160

t = 1/6

Hi,
10 feet in width requires 1/10 feet in length to move through for covering ONE sq ft..
2160 feet in 3600 secs....
Or 1/10 in  \frac{3600}{2160*10}=1/6 ...

Or 
2160*10 square feet in 1hr or 3600 secs..
1sq ft in 3600/21600 that is 1/6 secs..

A

we have 10*2160 square feet carpet moving under the dryer for 3600 seconds. we need to find the time to move 1 sq. feet of carpet through the dryer => let the time required be x Therefore (2160*10)/3600 = 1/x x = 3600/21600 = 1/6 Hence Option A is correct. Hit Kudos if you liked it. 8-)

Given

• At a certain carpet factory, carpeting of width 10 feet is moving continuously through a dryer at a constant speed of 2160 feet per hour.

To Find

• SECONDS it takes for an area of 1 square foot of carpeting to move through the dryer.

Approach and Working Out

• In an hour it would cover 10 × 2160 ft2.
• To cover 1 ft it should take  \frac{1}{(10 × 2160)}  hours
 o =  \frac{3600}{(10 × 2160)}  seconds
o = \frac{1}{6}  seconds.

Correct Answer: Option A

ScottTargetTestPrep · Answer

Solution:

1 square foot of carpeting has length of 0.1 ft if the width is 10 feet. Since the speed of the carpeting moving through the dryer is 2160 feet per hour, it’s moving at 2160/3600 = 0.6 feet per second. Therefore, it takes 0.1/0.6 = 1/6 of a second to move 1 square foot of carpeting.

Answer: A

Archit3110 · Answer

work = rate * time
rate per hour = 2160 
rate per seconds = 2160/3600 ; 0.6
work done for 10 feet ; need to determine rate for 1 square feet ; i.e. 1/10 
rate for 1/10 will be 
1/10 = r*0.6
r=1/6
option A
