Respuesta :

Answer:

It would take Vanessa 12 minutes

Step-by-step explanation:

Tobias peels 1.5 apples a minute

1.5 x 12 = 18

Take 1.5 apples and multiply it by 20 minutes = 30 apples

Vanessa peels 1 apple in 2 minutes

24 divided by 2 = 12

It would take Vanessa 48 minutes to peel 24 apples.

Tobias can peel 18 apples in 12 minutes. Therefore:

Number of apples peeled by Tobias in 1 minute = 18 apples / 12 minutes = 1.5 apples per minute

In 20 minutes:

Number of apple peeled by Tobias = 1.5 apples per minute * 20 min = 30 apples

Since Tobias and Vanessa can peel 40 apples in 20 minutes. hence:

30 apples + apples peeled by Vanessa = 40

Apples peeled by Vanessa = 10

Vanessa peeled 10 apples in 20 minutes at a rate of 2 minute per apple.

To peel 24 apples:

Time taken = 24 apples * 2 minute per apple = 48 minute

It would take Vanessa 48 minutes to peel 24 apples.
