In the local community center's carpentry club, 3 children can build a model of a boat in 10 days. Working together, 5 adults can build the same model in 3 days. At the same rates, if 2 children and 2 adults work together ideally, how many days will it take them to build the boat model?
Answers
Answer:
They will build in 5 days
Step-by-step explanation:
1 kid - 30 days = 1 boat, 2kid = 15 days = 1 boat
1 adult = 15 days = 1 boat, 2 adults = 15 days = 2 boats
2kid + 2 adults = 15 days = 3 boats, then 1 boat in 5 days

Answer:Number of days they will take to build the boat model
Step-by-step explanation:
Given: In the local community center's carpentry club, 3 children can build a model of a boat in 10 days. Working together, 5 adults can build the same model in 3 days.
To find: We have to find how many days will it take them to build the boat model.
Step 1: As 3 children can build a model of a boat in in 10 days.
∴ 1 children can build a model of a boat in in 30 days.
Step 2: As 5 adults can build the same model of a boat in in 3 days.
∴ 1 adult can build the same model of a boat in 15 days.
Step 3: If 2 children work together to build a model of a boat, so they will take 15 days to build 1 boat.
i.e. 2 children = 15 days
Step 4: If 2 adults work together to build a model of a boat. So they will take 15 days to build 2 boat.
i.e. 2 adults = 15 days
Step 5: If 2 children and 2 adults work together. So they will take 15 day to build 3 boat.
i.e. 2 children + 2 adults = 15 days = 3 boats
∴ Number of days they will take to build the boat model
