30 mph = 13.41 meter/sec 60 mph = 26.82 meter/sec 100 kph = 27.78 meter/sec
The average speed is 5 metres per second.

A 10.49-second 100-meter dash equates to an average speed of 21.32 miles per hour.

Speed = Distance/Time = 5 metres per second
If it falls for a greater height, the pull of gravity has more time to speed it up. Without air resistance, gravity speeds an object up by 9.8 meter/second2, or 9.8 meter/second/second; that means that every second, the speed increases by 9.8 meter/second. Another point of view is that at a greater height an object has more potential energy; when the object falls, this is converted into kinetic energy. To have more kinetic energy, the object must fall at a greater speed.

No. Average speed is the rate an object is moving measured over more than an instant, such as one second, one minute, or something like that. Instantaneous speed, however, is the limit of the average speed as the interval of time approaches zero, i.e. at a given instant.

You divide the distance by the time. If the time is in seconds, the average speed will be in meters/second. Multiply this by 3.6 if you want to have it in km/hour.
