You record the various speed on the same distance and sum it.
Then divide that sum with how many times you record it.
Like for x meters :
1. a m/s
2. b m/s
3. c m/s
.
.
n. y m/s
The average would be : (a+b+c +...y)/n

How does the shape of a plane's wing reduce drag?
A wing that is swept back reduces drag, but sacrifices stability at low speeds. Straight-winged aircraft produce the most drag, but are the most stable at low, landing speeds. The F-111 and F-14, with variable geometry wings, benefit from both aspects.
Why are airplane flaps not used at cruising speeds?
Because although flaps create extra lift they also produce a lot of extra drag which makes the plane inefficient.
What is drag force and what are its factors on which it depends?
Drag force is the resistance to motion of the object offered by the medium through which it travels, its value depends on the viscosity of the medium, and the shape, size and surface texture of the object. Note: for any given object, the drag force is equal to the square of the velocity * the drag coefficient of the object (rolling resistance is extra in the case of cars etc.)
How is an airfoil shaped?
Each aircraft has a different shaped airfoil. The purpose of the airfoil shape is to reduce drag over a range of speeds which the aircraft wing operates at while providing the least possible drag at the cruising speed (regular flight speed) in order to ensure good performance.
What will happen if friction disappeared?
If friction vanishes suddenly then,Movement on the ground will be impossiblewriting,typing, etc will be also not possible.wind will uproot the tree and plantsa body won't be able to change its direction and state of motion until an external force is applied on it.
How many cars in a drag race?
2
Do hamster drag racing cars exist?
no
How does the width of a car affect its air resistance?
When an object travels through an atmosphere, it encounters resistance from that atmosphere which is known as drag. objects such as bullets, aircraft and cars are shaped so that they produce less drag as they travel at higher speeds than if they were square or blunt objects. The width of a car does affect the drag it produces, but not nearly as much as the shapes of its leading and trailing edges.
Why are wings used on racecars if they produce lift on planes?
If that wing is turned upside down, it increases drag instead of lift. Race cars use this increased downward force to give them more traction at higher speeds.
How do you trade cars on drag racing for android?

What are the skinny drag racing cars called?
A Rail.
How fast do racing boats go?
drag boats have seen speeds of 250 mph +
Why are the drag coefficients of Formula 1 cars higher than normal cars?
Formula 1 cars have high drag coefficients because they are open wheel, and they have large air dams and spoilers to create downforce.
Why are drag cars so powerful?
Drag cars are quite powerful because of both the engines used to run them -- which are built for power and unnecessary in a standard vehicle -- and the fuel used to run them. Most drag cars race on a combination of fuels known as "racing alcohol" rather than standard gasoline. In addition, the design and tire placement of the cars help keep the cars powerful.
How does the shape of a plane's wing reduce drag?
A wing that is swept back reduces drag, but sacrifices stability at low speeds. Straight-winged aircraft produce the most drag, but are the most stable at low, landing speeds. The F-111 and F-14, with variable geometry wings, benefit from both aspects.
