conversations.value: It takes a dog groomer 10 minutes to dry a short-haired dog like a beagle.  It takes him twice as long to dry a full-haired, fluffy dog like a german shepherd.  One morning, he has 6 short-haired dogs to dry and 9 full-haired dogs to dry.  How many hours does it take him to dry all of the dogs?
  Give me a solution to this problem

conversations.value: It takes 10 minutes to dry the coat of a short-haired dog and twice as long for a full haired dog so they take 10*2 = 20 minutes to dry
  He had 6 short hair dogs and they took 10 minutes to dry each so they took 6*10= 60 minutes to dry
  He had 9 full haired dogs that took 20 minutes to dry each so they took 9*20 = 180 minutes to dry
  Together is takes him 60+180 = 240 minutes to dry all of the dogs
  60 minutes are in 1 hour and he spends 240 minutes on the dogs so he worked for 240/60 = 4 hours drying the dogs
