You can get speed or velocity by dividing distance moved, by the time it takes to move that distance.
velocity = distance / time There are also some formulae involving acceleration; for example, in the case of constant acceleration: velocity = initial velocity + acceleration x time If the acceleration is not constant, an integral is used instead.
Such formulae are usually given for acceleration; NOT for speed. The relevant formula is:a = dv/dt That means, acceleration is the rate of change of velocity, with respect to time. For constant acceleration (or for short time intervals), you can also write this as: a = delta v / delta t (change in velocity divided by the time interval)
There are different formulae for calculating these variables which depend on what information is available.
Speed in a given direction is velocity.
SPEED has the speed only; while VELOCITY has the direction and the speed.

Part of every velocity is a speed. Speed is the size of the velocity.But the velocity also has a direction, which the speed doesn't.'30 mph North' and '30 mph West' are the same speed but different velocity.
Speed in a given direction is called velocity.
Speed is a scalar, velocity is a vector. In other words, when the direction of the speed is relevant, it is called a velocity.
Velocity is speed and direction
Velocity is speed with a direction
It is the speed or velocity at a particular instant.
