The answer is 3 days.

In one day Mrs Hears knits 2/3 of a scarf, because
[tex] \frac{1}{3} + \frac{1}{3} = \frac{2}{3} [/tex]

To find the amount of days it costs Mrs Hewes to knit 2 scarves, we divide the amount of scarves in total, by the amount of scarves produced per day.

Therefore knitting 2 scarves costs him
[tex]2 \div \frac{2}{3} = \frac{2}{1} \div \frac{2}{3} = \frac{2}{1} \times \frac{3}{2} = \frac{6}{2} = 3[/tex]

Hence, knitting two scarves costs Mrs Hewes 3 days.
