Arsenal and Alexis Sanchez continued their fine record against Hull as Arsene Wenger's side won a third straight Premier League match for the first time since December.
The north Londoners were far from convincing in a midweek Champions League draw at Paris St Germain, just days after fortuitously overcoming Southampton, but matters were far more comprehensive at the KCOM Stadium.
Hull have only beaten the Gunners once since 1915 and that poor run was extended on Saturday, with Sanchez's double helping to secure a 4-1 win against a City side who were reduced to 10 men just before the break after Jake Livermore was sent off.
