Answer:
The machine takes 25 minutes to make 5 chairs. It would take the machine 160 minutes to make 32 chairs.
Step-by-step explanation:
Divide 2 chairs by 10 minutes to find the amount of chairs made per minute.
2/10 = 0.2 chairs per minute
Divide 5 chairs by 0.2 chairs per minute to find how much time it takes to make 5 chairs.
5/0.2 = 25 minutes
It takes the machine 25 minutes to make 5 chairs.
Divide 32 chairs by 0.2 chairs per minute to find how much time it takes to make 32 chairs.
32/0.2 = 160 minutes
It takes the machine 160 minutes to make 32 chairs.
