Answer:
36 minutes
Step-by-step explanation:
With the data given, we can calculate that if it takes 8 minutes to cut a board twice then, it takes four minutes to cut one board. We can then determine how long it takes the cut a board into 9 pieces by multiplying 9 x 4 to equal the amount that it takes for a board to be cut into 9 pieces which would be 36.
In conclusion, it would take 36 minutes to cut a board into 9 pieces.
Have a great rest of your day
