Hannah comes home from work to find her older son taped her younger son to a chair with 22 strands of duct tape. If Hannah can cut 8 strands per minute and her son can cut 3 strands per minute, how long will it take them to free her younger son?
How many strands can Hannah and her son cut per minute? ** First find the total number of strands the two of them can cut per minute: 8 strands + 3 strands = <<8+3=11>>11 strands
How many minutes does it take to cut all the strands? ** Then divide the total number of strands by the number of strands they cut per minute to find the number of minutes it takes to cut all the strands: 22 strands / 11 strands/minute = <<22/11=2>>2 minutes
