Because of the high heat and humidity in the summer in Death Valley, California, a hiker requires about 1 quart of water for every two miles traveled on foot. If the density of water is 0.999 g\mL at 45^oC , how many kilograms of water are required for a person to walk 30 kilometers in Death Valley? (1 L = 1.0567 qt; 1 km = 0.62317 mi)

First, convert 30 kilometers to miles: 30 km * 0.62317 mi/km = 18.6951 miles. A hiker needs 1 quart for every 2 miles, so for 18.6951 miles, they need 18.6951/2 = 9.34755 quarts. Convert quarts to liters: 9.34755 qt * (1 L / 1.0567 qt) = 8.844 L. Since the density of water is 0.999 g/mL, 8.844 L is approximately 8.844 kg (since 1 L = 1 kg for water). Therefore, the hiker requires about 8.8 kg of water.
