Mgbe ahụ kewaa ikike mmiri nke Violet na-ebu site n'ókè mmiri ha na-aṅụ kwa awa iji chọpụta awa ole ọ pụrụ ịga ije: 4.8 L / 1.2 L / hour = awa 4. Ya mere, azịza ikpeazụ bụ 4. <eng> First find the total amount of water Violet and her dog consume per hour: 800 ml + 400 ml = 1200 ml. 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.
