Project Summary: I have 2 Q's needs to be done within 4 hours DC zone Time. Thank you 1- How many liters of water would be saved if everyone in the United States who does not turn off the faucet while they brush their teeth, did so? Assume One-third of people leave water running while bushing. First, consider the following assumptions. In case of rough estimation, choose the most reasonable number which is closest to your own estimate. Show your work with unit conversions for full credit. Average number of tooth brushings per person per day is (5, 10, 0, 1). The population of the United States is (300 million, 75 billion , 75 million, 300 billion) Average time to bush teeth is (2, 20 , 10 , 0.2) minutes. Average faucet flow rate is ( 10, 0.2, 20, 2) gal/min. 2- If all the land (both currently inhabitated and all the inhabitable land) were divided equally among the people now living, how many acres of land would each one have? First, consider the following assumptions. In case of rough estimation, choose the most reasonable number which is closest to your own estimate. The diameter of the earth is (800, 12,000, 8,000 18,000) miles. The faction fraction of the total surface that is land is (0.1, 0.3, 0.5, 0.7, 0.9). The number of people on earth is (700 million, 35 billion, 7 billion, 70 billion, 900 million, 100 million).
