    So it's going to take more time for seven cooks?

    It only took five hours for six cooks, but it's going to take almost 6 hours for seven cooks? How does that make sense?

    5 hrs at 6 cooks is 30 cook hours. if 7 cooks work then 30/7 is the number of hours

    OK So this can be a little difficult to understand -- so let's show it this way: If 6 cooks do it on 5 hours, how long would it take 1 cook? 5 hours = time for one cook / 6 cooks 30 = time for one cook So if it takes 1 cook 30 hours, how long would it take 8 cooks: 30 hours for 1 cook / 8 cooks = 3.75 hours or 3 hours and 45 minutes. Hope this explanation is helpful.

    I think its inverse variation, since if you have more cooks it takes less time. 5 = k/6 k = 30 x = 30/7 = 4.28
