/ˈækʧuəl spiːd/ – Phrase
Definition: tốc độ thực tế.
A more thorough explanation: “Actual speed” refers to the true or real rate of motion or velocity of an object or vehicle, as measured in a specific unit of distance per unit of time. It is the factual speed at which something is moving, as opposed to an estimated or calculated speed.
Example: The driver was cited for exceeding the posted speed limit, as their actual speed was measured at 75 miles per hour in a 55 miles per hour zone.
