According to the United States Census Bureau, on September 1, 2014 the population of the United States was increasing by 1 person every 12 seconds. At this rate, by how much would the population of the United States increase in 1 year?

Remember that

`1\ hour=3,600\ seconds\\1\ day=24\ hours\\1\ day=(3,600)(24)=86,400\ seconds\\1\ year=365\ days\\1\ year=(365)(86,400)=31,536,000\ seconds`

using proportion

x ----> the number of persons

`(1)/(12)\ (person)/(sec)=(x)/(31,536,000)\ (person)/(sec)\\\\x=31,536,000/12\\\\x=2,628,000\ persons`
