Umm.. no need to yell. We always answer questions as quickly as possible.
How long it takes is dependent on the knitting, the needle size, and the yarn you are using. Stockinette is just knitting a row, then purling a row. What exactly are you having problems with? It helps us help you if you give us more info when asking questions.
Note - stockinette curls naturally so if you are making a stockinette scarf use a border of garter, seed stitch or some other non curling stitch all around the stockinette.
