Answer 3

Assuming that you don't consume water in another form (juices, watermelon, cactus), severe dehydration can occur in as little as a day. In hot climates, few people can last more than 72 hours. The longest that an average person can survive is 7 or 8 days without water, and that is under advantageous conditions (cool, damp) that limit evaporation and reduce the loss from breathing.
