Divide the total distance by the total time to get the average speed.
Or, when you need the speed at a certain time, you can differentiate the fuction of distance(t) over time. This can be compared with dividing the distance (of a really really really short timespan) by the same really really really short timespan)
There are various ways of measuring speed, the simplest is to time the vehicle over a certain distance and then work out the average speed by D/t (D = distance, t = time) Other ways are via a speed or radar gun
Get a Garmin 200W GPS device. Mount it in the car and by the satelite you will know precisely what speed you are travelling. GPS devices are extremely accurate. I used one while traveling from Arizona to Oklahoma and found my car speedo was inaccurate by a few miles per hour, which is normal. This is the best way to measure speed if you have replaced your stock tires with different size tires.

Or you can do distance divided by time
Liam
The formula for calculating speed is:
Speed=
Distance
_______
Time
Pronounced: Speed equals Distance over Time!
I hope this is what you needed!
Thank you

As speed is displacement per unit of time, measuring the speed of an object requires the measure of its displacement (how far it moved) and the amount of time it took to move that distance. Note that this will give average speed, but will be the actual speed of an object if that object does not slow down or speed up over the interval in which the measurements are taken. This may sound complicated, but it really isn't that bad. Consider land speed records.
When a really, really fast vehicle is checked to find its speed to record land speed records, that vehicle is given a long stretch in which to accelerate. The vehicle then enters the "eyes" of the measuring equipment, and it travels across a fixed distance. The time it takes to make the transit is measured when the "eyes" on the other end record the vehicle's passage. That vehicle has gone a fixed distance and has taken a fixed amount of time to do so. A simple calculation can be performed to find its speed.
You can measure speed in miles per hr (mph) or kilometers per hr.
OR
A way you can measure speed is by using a stop watch so you can tell how long did it take you to run.
Any way you like, but most people stick to kilometres per hour (km/h) or metres per second (m/s).
For the speed of a moving object, you need to know the distance travelled and the time taken.
It is known as the vector.
The measure of an objects kinetic energy is Temperature
They would have to have different base velocities. One on the ground, the other in a moving vehicle.
The measure of the force of attraction between objects due to gravity is WEIGHT. ^_^
"speed" or "the speed"
It is known as the vector.
Velocity
Its average speed.
Not actually a gun, it is a hand held radar unit that can measure the speed of moving objects, such as cars, baseballs, etc.
To know the mass of objects
You measure the length of two objects, then you divide the lengths.You measure the length of two objects, then you divide the lengths.You measure the length of two objects, then you divide the lengths.You measure the length of two objects, then you divide the lengths.
The measure of an objects kinetic energy is Temperature
when you know both speed and direction of an objects motion you know the velocity of an object.
Volume of an object is a measure of the space occupied by objects.
No.Consider a grain of rice and a banana. If you threw these at someone so that they were moving at the same speed, their velocities would be the same.However, you would hardly feel the impact of the grain of rice but the banana would hurt.The force of the impact is a measure of the relative inertia of the two objects.Where two objects are traveling at the samevelocity, the inertia is greater in that object that has the greatest mass.
To measure length around objects.
The speed varies according to the refractive index of the objects.
