James works for 240 minutes. He takes a water break every 20 minutes and a sitting break every 120 minutes. How many more water breaks does he take than sitting breaks?
How many water breaks does James take? ** First find the number of water breaks James takes: 240 minutes / 20 minutes/water break = <<240/20=12>>12 water breaks
How many sitting breaks does James take? ** Then find the number of sitting breaks James takes: 240 minutes / 120 minutes/sitting break = <<240/120=2>>2 sitting breaks
How many more water breaks does James take than sitting breaks? ** Then subtract the number of sitting breaks from the number of water breaks to find the difference: 12 breaks - 2 breaks = <<12-2=10>>10 breaks
