Answer: 93 years
Step-by-step explanation: So the total amount of natural gas is 2,474 trillion cubic feet, and it uses 26.6 cubic feet PER YEAR. That means that we would have to divide 2,474 by 26.6, which will result in 93.0075188. 93.0075188 rounded to the nearest whole number of years will be 93, so the supply of natural gas will last 93 years.
