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 t
makvit [3.9K]

Answer:

3 hours 40 minutes.

Step-by-step 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 \frac{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}=\frac{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.
