The way to skip the next line terminator in an input file is with a call to
Skip_Line.

However, when using Text_IO for input from standard input, it's best to always
input an entire line at a time into a String, and then deal with the line in the
String. The fact that Get leaves a line terminator in the buffer wreaks havoc on
error handling.

Get_Speed : loop
   Ada.Text_IO.Put (Item => "Enter desired speed: ");

   Speed_Line : declare
      Line : constant String := Ada.Text_IO.Get_Line;

      Last : Natural;
   begin -- Speed_Line
      Speed_IO.Get (From => Line, Item => Speed, Last => Last);

      exit Get_Speed;
   exception -- Speed_Line
   when others =>
      Ada.Text_IO.Put_Line (Item => "Enter a valid speed.");
   end Speed_Line;
end loop Get_Speed;
