Then divide that amount by 1000 ml / L to convert it to liters: 1200 ml / 1000 ml / L = 1.2 L. Then divide Violet's carrying capacity by the amount of water they drink per hour to find how many hours she can hike: 4.8 L / 1.2 L / hour = 4 hours. So the final answer is 4. <hau> Da farko ka samu adadin ruwan da Violet da karenta suke sha a awa daya: 800 ml + 400 ml = 1200 ml.
