From Multi Theft Auto: Wiki

This function allows you to get element speed in kph or mph units.

Syntax

int/bool getElementSpeed (element theElement, [ int/string unit="kph" ])

Required Arguments

• theElement: Element you want to get speed of

Optional Arguments

NOTE: When using optional arguments, you must supply all arguments before the one you wish to use. For more information on optional arguments, see Optional Arguments.

• unit: Units in which speed should be returned. This can be 1 or "mph" for mph, any other value for kph.

Code

function getElementSpeed(element,unit)
	if (unit == nil) then unit = 0 end
	if (isElement(element)) then
		local x,y,z = getElementVelocity(element)
		if (unit=="mph" or unit==1 or unit =='1') then
			return (x^2 + y^2 + z^2) ^ 0.5 * 100
		else
			return (x^2 + y^2 + z^2) ^ 0.5 * 1.61 * 100
		end
	else
		outputDebugString("Not an element. Can't get speed")
		return false
	end
end

Example

addCommandHandler("getmyspeed",
function (player, cmd)
  outputChatBox ("Your speed in mph: "..getElementSpeed(player, "mph"),player)
  outputChatBox ("Your speed in kph: "..getElementSpeed(player, "kph"),player)
end
)
