 This is also expressed in terms per 10 miles alargar.His alargar was 55, and his angle of return was ENE (thus q = 2), that means his avanzo di ritorno is 5.5 × 24 = 132.In other words, if everything goes right, and our mariner holds his ENE bearing for 143 miles ("ritorno"), then during that return, he will have covered an additional 132 miles on his intended eastward course ("avanzo di ritorno").
