Leeds finally recorded their first league win of the campaign with an impressive performance against Hull.
Ross McCormack headed United into the lead before Tom Lees put through his own net after inadvertantly converting Robbie Brady's cross.
Lees made amends when he was on hand to poke in after Ramon Nunez's ball from a corner was spilled by Peter Gulacsi.
Robert Snodgrass added a third with a 25-yard free-kick before Nunez made it 4-1 with a precise finish.
The win places Leeds in 13th while Hull are in 18th spot.
Scotland winger Snodgrass had an excellent game and went close when he forced Gulacsi to scramble at his near post.
Hull then failed to deal with a Snodgrass cross but Nunez sent a weak shot wide before new signing Andy Keogh cut inside and drilled an effort over the bar.
The visitors had few clear-cut chances in the match. Substitute Aaron McLean had their best opportunity of the second half, but his header at the back post was comfortably saved by Andy Lonergan.
