This is called free trade. Free trade occurs when there are relatively few tariffs imposed on countries for the importation of goods. Completely free trade in this sense, however, is rare.
the Treaty of Brest-Litovsk was a peace treaty signed on 3 March 1918 between the new Bolshevik government of Soviet Russia and the Central Powers (Germany, Austria-Hungary, Bulgaria, and the Ottoman Empire), that ended Russia's participation in World War I. The treaty was signed at Brest-Litovsk (Polish: Brześć Litewski; since 1945 Brest), after two months of negotiations. The treaty was agreed upon by the Bolshevik government to stop further advances by German and Austro-Hungarian forces. According to the treaty, Soviet Russia defaulted on all of Imperial Russia's commitments to the Triple Entente alliance
60*40=2400
the area of the square is 2,400 yards squared
2400 yards dived by 60 minuets is 40. So Dan cuts 40 yards per minuet
2400 yards dived by 40 minuets is 60. So Andy cuts 60 square yards per minuet
60*2= 120 40*2=80 120*80=9600
It would take Dan 240 minutes or 4 hours because 2600 dived by 40 yards per minuet is 240. It would take Andy 160 minutes because 9600 yards squared divided by 60 square yards per minute is 160.
