If one truck runs on 6000 barrels of oil per year, how many trucks could run on the oil produced in the US in one year (1.9*10^10 barrels)?
(6000 barrels/year) used by one truck
(1.9*10^10 barrels/year) for US production
The Attempt at a Solution
I simply divided 1.9*10^10 by 6000 to get 3,000,000.
I'm confused about the fact that 3,000,000 is not in units of "trucks". How can I set up this problem properly to include trucks as my units?
