{
    new Float:PosX;
    new Float:PosY;
    new Float:PosZ;
    GetPlayerPos(playerid, PosX, PosY, PosZ);
    new value;
    new Float:PlayerSpeedDistance;
    PlayerSpeedDistance = floatsqroot(floatpower(floatabs(floatsub(PosX,ReadPlayerPosition[playerid][ReadX])),2)+floatpower(floatabs(floatsub(PosY,ReadPlayerPosition[playerid][ReadY])),2)+floatpower(floatabs(floatsub(PosZ,ReadPlayerPosition[playerid][ReadZ])),2));
    value = floatround(PlayerSpeedDistance * 5000);
    new KPH = floatround(value/800);
    return KPH;
}

stock GetSpeedMP(playerid)
{
    new Float:PosX;
    new Float:PosY;
    new Float:PosZ;
    GetPlayerPos(playerid, PosX, PosY, PosZ);
    new value;
    new Float:PlayerSpeedDistance;
    PlayerSpeedDistance = floatsqroot(floatpower(floatabs(floatsub(PosX,ReadPlayerPosition[playerid][ReadX])),2)+floatpower(floatabs(floatsub(PosY,ReadPlayerPosition[playerid][ReadY])),2)+floatpower(floatabs(floatsub(PosZ,ReadPlayerPosition[playerid][ReadZ])),2));
    value = floatround(PlayerSpeedDistance * 5000);
    new MPH = floatround(value/1400);
    return MPH;
}
