Here, we need to compare Time with Work.
More Time we have, more Work can be done i.e. they are directly proportional
So, \(\frac{T_1}{W_1} = \frac{T_2}{W_2}\)
\(\frac{8}{8} = \frac{(18)(60)}{W_2}\)
\(W_2 = 1080\)
Hence, option A

Rate-Work Problem
The only formula you need to remember to solve this problem is Rate * Time = Work Done
A certain 3D Printer machine can make 8 Products every 8 seconds
=> Rate * 8 Seconds = 8 Products [work done]
=> Rate = \(\frac{8}{8}\) Products/second = 1 Product / Second
how many products can the machine make in 18 minutes
Rate * Time = Work Done
1 Product/second * 18 minutes = Total Products
=> Total Products = 1 * 18 * 60 products = 1080 Products [because 1 minute = 60 second]
So, answer will be A
Hope it helps!
