But is it takes 10 minutes to cut 2 pieces, that would mean that it was 5 minutes per piece. So one piece equals five minutes, two pieces equals ten pieces, and three pieces equals 15 pieces. It’s going by 5’s, so the teacher was correct.

No, Brenda, the student was correct. One cut took ten minutes. In order to get three pieces, two cuts need to be made. Two cuts at ten minutes for each cut really does equal 20 minutes.

This is a tricky question.
In fact both the teacher AND te student might be right (also Brenda and Lori). What the teacher forgot to specify is if the table was round or rectangular/square!!!!
If it is a rectangular table, both the student and Lori are right, it takes just the same time per cut (10 min x2= 20 minutes)
But if this is a round table, so the teacher and Brenda are right! Since the half (diameter) will take 10 minutes, and half of that piece (radius) would take HALF of the time, (diameter (10min)+ radius (5 min)= 15 minutes)
It is just about perspective…Still, the teacher should have approved the kid’s answer!
