Degger [83]

Answer:

18 minutes

Step-by-step explanation:

Sophie can peel all potatoes in 45 minutes, in 1 minute she can peel:

1/45 of all the potatoes

Simon can peel all potatoes in 30 minutes, in 1 minute he can peel:

1/30 of all the potatoes

Together, in 1 minute they can peel:

1/45+1/30= 2/90+3/90= 5/90= 1/18 of all the potatoes

To peel all the potatoes they need:

1 ÷ 1/18= 1 × 18= 18 minutes

So it will take them 18 minutes to peel all the potatoes
