If it takes 3 minutes for 4 pieces then to find how many minutes it takes for 1 piece.
Therefore, 4 divided by 3 = 1.333333333
Then, we have to multiply 1 into how many pieces we want,i.e, 15.
Hence, 1.333333333 into 15 = 20
Therefore, it will take the man 20 minutes to cut the wooden plank into 15 pieces.
