Sophie and Simon are peeling a pile of potatoes for lunch in the cafeteria. Sophie can peel all the potatoes by herself in 45 minutes, while it would take Simon 30 minutes to do the job working alone. If Sophie and Simon work together to peel the potatoes, how long will it take them?

    You can already rule out the last two options because Simon can do the job in 30 minutes. It wouldn't make sense if it took him longer to peel the potatoes with the help of someone else.
