   12.  
       1. To solve this question, substitute 5906 for d in the equation.
          
          
           
          
          
          Solving for the equation yields
          
          
           
          
          
          

          Thus, to the nearest Earth year, it takes Pluto 248 Earth years to revolve around the sun.

       2. To solve this question, substitute 1.88 for T in the equation.
          
          
           
          
          
          Solving the equation yields
          
          
           
          
          
          Thus, Mars, to the nearest million kilometres, is 228 million km from the sun.
