conversations.value: Ellis is going to take a road trip with her family. First, she needs to figure out how many bottles of water she should bring for everyone. There will be four people total: Ellis, her mother, her sister, and her aunt. They will be on the road to their destination for 8 hours and drive 8 hours to return home. Every hour each person will want to drink 1/2 a bottle of water. How many water bottles will Ellis' family need total?
  Give me a clear explanation.

conversations.value: Ellis and her family of 4 will be traveling for 8 hours going and 8 hours coming home = 16 hours total.
  Each person needs 1/2 a bottle of water each hour, so 1/2 a bottle x 16 hours = 8 bottles.
  There are 4 people traveling so 8 total water bottles for each person x 4 people = 32 total water bottles.
