Question

You plan to put anti-theft devices on each garment in your store. You have 1,320 garments, and it takes an employee 20 seconds to tag a garment. How long will it take TWO employees to tag all the garments?

Answer 1

13,200 Seconds, or 220 Minutes

Explanation:

Since there are 2 employees working at the same time, so in 20 seconds, they will be tagging a total of 2 garments. So we can say the rate is:

rate =
`(20 Seconds)/(2 Garments)`

So how long would it take to tag 1320 garments?

We set up the ratio, cross multiply, and solve.

`(TimeInSeconds)/(NumberOfGarments)=(20)/(2)=(x)/(1320)}\\(20)/(2)=(x)/(1320)\\20*1320=2x\\x=(26400)/(2)=13,200` seconds

Or in minutes, we divide by 60, so we have:

`(13,200)/(60)=220` Minutes

Answer 2

3 hours 40 minutes.

Explanation:

We are told that we have 1320 garments and it takes an employee 20 seconds to tag a garment.

1 employee tags one garment in 20 seconds.

So garments tagged by 1 employees in 1 minute will be
`(60)/(20) =3` garments.

2 employees will tag 3*2=6 garments in 1 minute.

To find the total time it will take two employees to tag all the garments we will divide total number of garments by 6.

`\text{Time taken by two employees to tag 1320 garments}=(1320)/(6)`

`\text{Time taken by two employees to tag 1320 garments}=220`

Therefore, it will take 220 minutes or 3 hours and 40 minutes for 2 employees to tag 1320 garments.
