How long ...??

How long someone can survive without water in an african country
But only eating sold food

well if your runind low on food it is not sutch a good I dea to eat a lot because when you eat that uses more watter but normaly a person can only live 2 to3 days without water but in that case I wouldnt eat to preserve water

What African country, at what temperature? You do know that not all of africa is scalding hot right?

And jessika berry is pretty much correct.
