Velocity is a vector: it has a direction. The others are all scalars.
The dimensions of the scalars are
Speed : [LT-1]
Time: [T]
Distance: [L]

What is the formula for working out distance?
As speed=Distance/time, distance would be, distance = Speed x time or, s = vt where s is distance, v is speed or change in velocity and t is time
How do you calculate velocity final with distance?
Distance alone is not enough to tell you velocity final. (If it could, then all of the thousands of runners who finish in the same marathon would all cross the finish line at the same speed.) Besides distance, you would also need velocity initial, and either acceleration or time.
How would you find the average speed of a cyclist throughout an entire races?
Velocity, you divide distance/time Hi my names bob.
What type speed is represented by a constant slope on a distance time graph?
The slope (technically, the slope of the tangent at each point) of a distance-time graph gives the instantaneous velocity. Therefore, if the graph has a constant slope - i.e. it is a straight line - then that indicates a constant velocity (zero acceleration).
Why is it not possible for any part of the distance-time graph of a body to be a straight-line segment parallel to the distance axis?
BecAuse that would mean it is going an infinite speed. The slope of a distance time graph is the objects velocity or speed. If there is a line parallel to the distance axis, there is a vertical line. The slope of a vertical line is infinite. It is not possible to go an infinite speed.
How would you differentiate between speed and velocity?
Speed is the magnitude of distance travelled per unit time, whereas velocity depends on the magnitude of distance travelled as well as the direction of motion. Speed is a scalar quantity, velocity is a vector. Speed cannot be negative, velocity can be negative. Average speed of an object after travelling a certain distance is always non-zero, but for velocity the average velocity can be zero (this follows from the previous idea).

What would happen if a projectile were thrown with greater velocity?
A projectile thrown with a greater velocity would travel a greater distance. Velocity is not just speed but direction as well.

How do you calcuate speed or velocity?
Speed and velocity are different. Speed is how fast something's moving. Velocity is speed combined with the direction the thing is moving. Speed is calculated by dividing the distance traveled by the time it took to travel this distance. For example, if you drove 100 miles in two hours the speed would be 100 divided by 2 or 50 miles per hour.
What is the type of speed that is distance moved per unit of time?
Distance / time is simply called "speed". When the direction is relevant, you would talk about "velocity". I am not aware of different "types of speed".
How is the speed of moving object measured?
Speed is measured by dividing your time into distance to come up with your velocity. speed is measured the same way as velocity. If you have a varying speed with acceleration and deceleration this would need to be factored in as well.
Is speed always measured in terms of a unit of distance divided by a unit of time?
The unit is called 'speed'.
What is speed in calculus?
Speed is an example of a rate of change. It is specifically the rate of change of distance over time.In calculus, speed is the absolute value of velocity. Velocity measures both speed and direction, while speed only measures speed. For example, if a car is driving backward with a speed of 90km/h, its velocity would be -90km/h because "backward" indicates a "negative" velocity.
How do you calculate velocity final with distance?
Distance alone is not enough to tell you velocity final. (If it could, then all of the thousands of runners who finish in the same marathon would all cross the finish line at the same speed.) Besides distance, you would also need velocity initial, and either acceleration or time.
Change In Distance Over Time?
It is purely a distance. If you say 5 miles per hour that is called a velocity, or speed. So the distance is velocity times time. If the velocity changes during the time interval, the distance is the sum of all the tiny distances multiplied by the velocity at each interval. If the path is curved, that's still OK, but the final distance from the start point will be less, and could even be zero.
