I was just wondering if someone could take a look at this question and take a look at how i worked it out and if they thought it looks right.
The worlds total proved reserves of oil have recently been estimated at 1,200,000 million barrels. The worlds total consumpetion of oil this year is estimated to be about 31,025 million barrels. If consumption increases by 1.5% per annum, and no new sources are discovered, how many more years will the reserves last?
THe answer I got was 244 years, does that look reasonable?
Thanks for your time
