Detailed explanation-1: -Speed of a body is the distance covered by the body per unit time i.e. Speed = Distance/Time. Speed: Speed is the rate at which a particular distance is covered by an object in motion. Time: Time is an interval separating two events.
Detailed explanation-2: -Speed is the ratio of the distance an object moves to the amount of time the object moves. The SI unit of speed is meters per second (m/s). Two ways to express the speed of an object are average speed and instantaneous speed.
Detailed explanation-3: -The basic formula says Speed= Distance/Time . From this formula, it is evident that speed is directly proportional to distance and inversely proportional to time.
Detailed explanation-4: -Average Speed-the average of all instantaneous speeds; found simply by a distance/time ratio.
Detailed explanation-5: -The speed of an object is the distance the object moves per unit of time. Speed is a type of rate.
