Time played has NOTHING to do with Elo gain. Your elo is gained based on mathematical values of your "likely-ness to win" vs. "enemy and team member skill level"

ELO is not specific to League of legends; for more information research the E.L.O ranking system (It's very common in mainstream sports as well)
