A pair of socks takes 1.5 hours per sock * 2 socks = 3 hours. So a complete outfit for each child takes 2 hours per hat + 3 hours per scarf + 2 hours per pair of mittens + 3 hours per pair of socks + 6 hours per sweater = 16 hours per outfit. So to knit winter outfits for all three of her grandchildren, Martha will take 3 outfits * 16 hours per outfit = 48 hours. Final answer: 48.
