I am having trouble thinking through these problems. :lol:

If two typists can type two pages in two minutes, how many typists will it take to type 18 pages in six minutes?

Just set up the proportion.

$$\displaystyle \frac{\text{number of pages}}{\text{(number of typists)(minutes)}}$$

The number of pages per typist-minutes.

$$\displaystyle \frac{2}{2\cdot 2}=\frac{18}{k\cdot 6}$$

solve for k.

You may find this problem and similar ones if you google 'work problems'.

galactus, I was wondering if there is a certain formula for this. It looked like you used a formula. If so, can you write it down.

Thanks

Not a particular formula. Just use of proportions. Depends on the problem. Forget formulas and try thinking it through.
