Kalinda is working on a 360 piece puzzle with her mom. Kalinda can normally add 4 pieces per minute. Her mom can typically place half as many pieces per minute as Kalinda.  How many hours will it take them to complete this puzzle?
How many pieces does her mom place? ** Her mom places 2 pieces per minute because 4 / 2 = <<4/2=2>>2
How many pieces do they get in? ** On average they get in 6 pieces per minute because 4 + 2 = <<4+2=6>>6
How many minutes will it take them to complete the puzzle? ** It will take 60 minutes to complete the puzzle because 360 / 6 = <<360/6=60>>60
How many hours will it take them to complete the puzzle? ** It will take one hour because 60 / 60 = <<60/60=1>>1
