    is there more information... it seems like it would depend on the strength of the person

    Are we assuming that these people all have the same strength?

    It's a ratio then. 3 people to 2 people is x hours to 6 hours: 3/2 = x/6. Do the algebra, you get 3x = 12, which means x (the number of hours it will take with 3 people) = 4.

    four hours... i think (2ppl)(6hrs) = (3ppl)(xhrs) x hrs=4
