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

Determine the required time:

Given, $5$ machines makes $5$ widgets in $5$ minutes of time.

$1$ machines makes $5$ widgets in $5\times 5=25$ minutes of time.

$1$ machines makes $1$ widgets in $\frac{25}{5}=5$ minutes of time.

So, $1$ machines makes $100$ widgets.in $5\times 100=500$ minutes of time.

$100$ machines makes $100$ widgets.in $\frac{500}{100}=5$ minutes of time.

Hence, it would take $100$ machines to make $100$ widgets $5$ minutes of time.
