A map has a scale of 1 inch representing 50 miles. If a journey from City X to City Y measures 3.5 inches on the map, how many miles is the actual journey? Additionally, if another route from City X to City Z measures 6 inches on the map, how many miles is this route in kilometers? (Use the conversion factor: 1 mile = 1.60934 kilometers) Let's think step by step and output the final answer within \boxed{}.
