**Question description**

Jeff is the chief rhinoceros caretaker at the Red River Valley Zoo. He has just arrived at the cargo dock in the local freight yard. In order to pick up four members of the endangered species rhinocerosium mathematicus recently rescued from poachers in Africa. In order to complete the paperwork, he needs to weigh them, but the only scale big enough to the weight the rhinos is a the truck scale that starts at 300 kilograms, more than what one of any of the individual rhinos weighs. Jeff is puzzled for a few minutes, then gets the idea of weighing them in pairs, thinking that if he gets the weight of every pair he can figure out the weight of the individual rhinos. He compiles the weights pair by pair, getting 312,356,378,444, and 466 kilograms. As he tries to weigh the heaviest pair of rhinos, the scale breaks. Does jeff have enough information to find the weight of each rhino? If so, find the weight of each rhino, and if not, state why finding all the weights of the individual rhinos is impossible with the given information.
