Answer 2

can u show me ur work please?

Answer 3

yeah, you've already peeled 8 potatoes, and because you can peel 2 per minute, you have taken 4 minutes. But originally, before you started, it would have taken you 10 minutes to peel all the potatoes. So, you take the 10 minutes totally needed - the 4 minutes already taken up. So, you end up with 6 minutes left of peeling to do.
