A machine makes 150 boxes in 15 minutes what is the rate

Since 150 is divisible by 15, you could easily divide 150 by 15.

So, your answer is 10, because

15 X 10 Equals 150.

Also, to check your work, you could always add.

15+15=30. 30 X 2 Is 60 (15 X 4) 60 X 2=120, (15 X 8) and 15 X 2 = 30. Which is added up to 30+120, which is 150.

So your answer is 10

I think its 10 boxes per minute but i could be wrong ...
