Катер плив проти течії річки швидкістю 27,3 - 1,9 = 25,4 км/год протягом 2,6 годин і проплив відстань 66,04 км. Катер плив за течією річки швидкістю 27,3 + 1,9 = 29,2 км/год протягом 1,6 годин і проплив відстань 46,72 км. Різниця між цими відстанями дорівнює 66,04 - 46,72 = 19,32 км. Отже, катер проплив на 19,32 км більше, рухаючись проти течії, ніж за течією.
