## Task 1 - 260721

Anne, Bernd, and Peter help in the garden during the apple harvest. All three use baskets of the same size. Anne needs 10 minutes to fill a basket, Bernd takes 15 minutes, and little Peter even 30 minutes.

How long would it take for the three children to fill a basket together?

We assume that the picking speed does not change for any of the three helpers.
Anne has filled $\frac{1}{10}$ of her basket in one minute, Bernd $\frac{1}{15}$, and Peter $\frac{1}{30}$. Together, they have filled

$$
\frac{1}{10}+\frac{1}{15}+\frac{1}{30}=\frac{1}{5}
$$

of a basket after one minute. Thus, they need 5 minutes together to fill one basket.
