c. Where is the oil sands deposit located in Alberta, Canada? d. Why is the extraction rate of the oil sands deposit estimated to be approximately 1 million barrels of bitumen per day?

1. To figure out how many days will be needed to extract the recoverable volume of bitumen from the oil sands, you will need to divide the total volume of recoverable bitumen (73 billion barrels) by the rate of extraction (1 million barrels per day). So, 73,000,000,000 barrels ÷ 1,000,000 barrels/day = 73,000 days. a. Yes, there is a ratio in this problem. The ratio is the relationship between the total volume of recoverable bitumen (73 billion barrels) and the rate of extraction (1 million barrels per day). This ratio can be written in two different ways: - 73 billion barrels: 1 million barrels/day - 1 million barrels/day : 73 billion barrels b. The ratio you would use to obtain the desired answer (the number of days needed to extract the bitumen) is the total volume of recoverable bitumen to the rate of extraction (73 billion barrels : 1 million barrels/day). By dividing the total volume of bitumen by the extraction rate, you will get the total number of days needed for extraction which is 73,000 days.
