                    SendClientMessage(playerid, COLOR_YELLOW, string);

                }
                else SendClientMessage(playerid, COLOR_WHITE, "[ERROR]No Such Player");
            }
            else SendClientMessage(playerid, COLOR_WHITE, "[ERROR]Player Not Connected");
        }
        return 1;
    }

Thats how I would do it. Shows MPH and KPH.

So:

pawn Код:

floatmul(floatsqroot(floatpower( Pos X ,2) + floatpower( Pos Y ,2) + floatpower(Pos Z ,2)), 200);
