The basement of a shopping mall has 4 levels (\(\textbf{B}\hspace{0.5em}1\) to \(\textbf{B}\hspace{0.5em}4\)). Each level is \(3\textbf{ m}\) high. If Level 1 is represented by \(0\textbf{ m}\):

  1. What is the integer representing the floor of \(\textbf{B}\hspace{0.5em}3\)?
  2. An elevator travels from \(\textbf{B}\hspace{0.5em}4\) to Level 5. If each floor above ground is also \(3\text{ m}\) high, what is the total distance traveled?
