I have a wooden chopping board about the same size and shape as a pizza.
If it took 10 minutes to saw a board into 2 pieces, how long would it take to saw another board into 3 pieces?

A circular wooden chopping block with many scratches in the wood grain. A small knife with black handle rests on it.
Question 4 (three stars) says "It took Marie 10 minutes to saw a board into 2 pieces. If she works just as fast, how long will it take for her to saw another board into 3 pieces?" A student has written the answer: 20 minutes A teacher has marked it wrong in red ink arguing the answer is 15 minutes. 10 minutes for 2 pieces, 15 for 3, 20 for 4 A figure accompanying the question shows a saw cutting a long rectangular beam of wood
