US oil consumption in 2006 was 20,588,000 barrels/day (Wikipedia), = 2.0588 x 107. 112 billion = 11.2 x 1010. So this would last 11.2/2.0588 x 103 days = 5.44 x 103 days or 5,440 days = 14.9 years.
The US has about 30 Billion barrels of proven oil reserves. If assume use no oil imports (US imports about 60% of use currently) and current rate of consumption (oil use in US has recently begun to go down) of about 20.7 Million Barrels a day - US oil proven reserves will be drained in about 4 years. If use current levels of import, the current reserves will last about 10 years. If add in estimated prospective oil reserves, the US has about 130 Billion Barrels (unproven) additional reserves. Of the 130 Billion Barrels, ~ 85 BBls are offshore (~20 BBls in currently off limits areas) and ~45 BBls under land (~10 BBls are in ANWR). The prospective reserves would last at current consumption levels about another 17 years (21 total) with no imports or about another 43 years (53 total) at current import levels. The US also has the largest formation of oil shale in the world, with an estimated 1.5 (some estimates are over 2) Trillion barrels of oil in oil shale in reserve or about twice the reserves of the entire middle east, but this oil is harder to get. If use 1.5 TBls with no imports, US has oil to last 200 years at current consumption with no imports and nearly 500 years if assume current import levels just from this source.
The Earth is about 4.5 billion years old. Life appeared on Earth about 3.5 billion years ago. The Earth would have been about 1 billion years old at that time.
The heavy bombardment period, known as the Late Heavy Bombardment, is estimated to have occurred about 4.1 to 3.8 billion years ago. This period was characterized by intense asteroid and comet impacts on the inner planets of the solar system, including Earth.
Waterspouts typically last a few minutes to up to an hour. They are generally short-lived phenomena that form and dissipate quickly.

half a billion years left. But that does not mean that PEOPLE will last that long. ;-)
The Sun has been living for approximately 4.57 billion years , and is expected to last for roughly 5 billion more, as it's lifespan is about 10 billion years. :D

1 billion years
2 billion seconds
That depends what the barrels are of and how much the individual barrels weigh.
It started about 4.6 billion years ago, and ended about 3.8 billion years ago.
it lasts about a ten billion years
Over the last 4 billion years.
