Question

If it takes 5 machines 5 minutes to make 5 widgets, how long would it take 100 machines to make 100 widgets?

Answer 1

It takes one machine 5 minutes to make 1 widget, and so 5 machines can make a total of 5 widgets. So I have 100 machines and I want to make 100 widgets, we already know that it takes 5 minutes to make 1 one widget so it should only take 5 minutes. The machines are all running at the same time no matter how many there are.

Answer 2

It would take 100 machines 100 minutes (1 hour and 40 minutes) to make 100 widgets.
It takes 1 minute to make each widget.
