Basic Function

I'm training for a half-marathon, but have to run a certain number of miles per hour to be able to qualify. Can I do it?

Two values get passed to the function in the order in which they are presented. The function returns one value to the program.

The Function:

Create Or Replace
 Function My_Speed
   (My_Mileage Number
   ,My_Time    Number
   )
Return Number
Is
Begin
  Return My_Mileage/My_Time;
End;
/

Calling the Function:

Begin
   DBMS_Output.Put_Line ('MPH: '
                        || My_Speed(&Miles,&Hours)
                        );
End;
/
