I'd say that the question needs to be retyped. It appears that it should read
If Mr. Cruz were 3 years older, he would be the same age as Mr. John. Mr. John is 46 years old. how old is Mr. Cruz now?
43 years old. DUH.
If I got it wrong, say (clearly) what is the question.
what is the graph of potential energy and kinetic energy against distance?
