Flora has been experiencing frequent fractures. Dr. Juan has asked her to strengthen her bones by drinking 105 gallons of milk within 3 weeks. Flora thinks that drinking 3 gallons of milk daily will be enough, but her brother says she'll still need to drink more. To fulfill Dr. Juan’s requirement, how many more gallons must Flora drink daily?
3 weeks translate to 3 * 7 days = <<3*7=21>>21 days.
To meet Dr. Juan’s recommendation would mean drinking 105/21 = <<105/21=5>>5 gallons daily.
This means that Flora must drink 5 -3 = <<5-3=2>>2 more gallons daily.
