  if you do a job in 4 hours, and your friend can do the same job but in 6 hours, and if you both work together how long will it take to complete the job?
  
  • math -
  
  friend's rate = job/6
  
  combined rate = job/4 + job/6 = 5job/6
  
  Time = job/rate = job/(5job/12))
  = 12/5 hours or 2 hours and 24 minutes.
