(1.5 cats --> 1.5 rats) in 1.5 days. (1 cat --> 1 rat) in 1.5 days It takes 50 cats (50/1.5) = (33 and 1/3)days to eat 50 rats.
3 minutes
Three minutes
3 minutes coz it takes 1 cat to kill one rat in 3 minutes
three and a half cats
5 minutes
10 cats For future reference, this problem is solved as follows: Let C1 be the number of cats who eat O1 rats in T1 minutes and Let C2 be the number of cats who eat O2 rats in T2 minutes C1T1/O1 = C2T2/O2 solve C2 = O2C1T1/O1T2 C2 = 100x5x5/ (5x50) = 10 cats
It would still take 3 minutes according to the setup of the question, assuming there are enough rats to make this work. It takes 1 cat 3 minutes to find a rat, and 3 minutes for 3 cats to each find a rat. So 100 cats would only take 3 minutes to find 100 rats. Time is irrelevant since the only factors changing are the cats and the rats. However, this question assumes too many things that would likely not happen. The question assumes an even density of rats, that the cat's are equally able to catch rats, and that there are enough rats.
It will take 3 minutes if you look at this problem mathematically. Both scenarios have a ratio of 1 rat to 1 cat. 3 minutes multiplied by 1/1 equals 3 minutes.
If you are talking about domestic rats, about 2-3 years, depending on how well you take care of it. Mine is pushing a year and a half.
Cats are very good at getting rid of rats. Just get a few cats and they'll take care of your rat problem.Actually, cats are not that good at catching rats: rats love water, and tend to live where there is lots of it (sewers, docksides, etc.) Cats hate water, but not only that, they are usually well fed and do not have the killer instinct of an animal looking for food. Ferrets, or better still, mink are far better rat catchers.

they can see in the dark and the have to be able to see very well to catch mice, rats, and rabbits
