Answer:
5 minutes
Explanation:
Given:
It takes five machines five minutes to make five widgets
Let's first determine how much time it takes one machine to make one widget
- 5 machines -> 5 widgets -> 5 minutes
1 machine will take 5 times as long to make 5 widgets
- 1 machine -> 5 widgets-> 5 * 5 minutes
1 machine -> 5 widgets-> 25 minutes
Therefore for 1 machine to make 1 widget it will take 1/5th of the time
- 1 machine -> 1 widget -> 5 minutes
To make 100 widgets, 1 machine will take 5 x 100 minutes or 500 minutes
- 1 machine -> 100 widgets -> 500 minutes
If we use 100 machines this time will be reduced by 100
- 100 machines -> 100 widgets -> 5 minutes
