Johnson owns a hectare cornfield that can yield 80 corn every two months, while his neighbor owns a two-hectare cornfield and each hectare can yield twice the amount as Johnson. How much corn can they harvest altogether after six months?
How many corns can each hectare of Johnson's neighbor yield? ** Each hectare of Johnson's neighbor can yield 80 x 2 = <<80*2=160>>160 corns every two months.
How many corns can the neighbor's two-hectare cornfield yield? ** So, the neighbor's two-hectare cornfield can yield a total of 160 x 2 = <<160*2=320>>320 corns every two months.
How many corns can they harvest altogether after six months? ** They yield a total of 80 + 320 = <<80+320=400>>400 corns.
How many corns can they harvest altogether after six months? ** Therefore, They can harvest 400 x 3 = <<400*3=1200>>1200 corns altogether.
