Here's the problem: 20 men dig 40 holes in 60 days. So, 10 men can dig 10 holes in how many days? I think the answer is 3 or 3 and 1/3, but I want to be sure. (An bet with my 10-year-old brother depends on it!)
Thanks for your help!
I think you are in trouble.
The solution to this problem is to imagine the situation and reason it out.
