Khoi no one to solve my logical problem? Ali overdose bha jasto cha sajha lai. Just repeat it for new readers There is a 200 mile distance in which runners are allowed to carry 2 gallons of water in 2 hands, thats it. The 1 gallons of water is enough for the runner to run 25 miles. He can go a certain miles and store gallons as many times as he likes provided he has enough water to get back to the start. He can come back and get maximum of 2 gallons. So he runs a certain distance and stores gallons of water, comes back to start get more water. What is the lowest number of trips he has to make back to make the 200 mile distance?
