A boat takes $2$ hours to travel downstream a river from port $A$ to port $B$, and $3$ hours to return to port $A$. Another boat takes a total of $6$ hours to travel from port $B$ to port $A$ and return to port $B$. If the speeds of the boats and the river are constant, then the time, in hours, taken by the slower boat to travel from port $A$ to port $B$ is

  1. $3(\sqrt{5}-1)$
  2. $3(3+\sqrt{5})$
  3. $3(3-\sqrt{5})$
  4. $12(\sqrt{5}-2)$
