Speed is a scaler quantity i.e. it has magnitude only without direction. It can be calculated using the formula :
speed = distance/time
where distance is the total distance travelled from initial position to final position;
time is the total time taken to cover this distance.
Velocity is a vector quantity i.e. it has magnitude as well as direction. It can be calculated using the formula :
velocity = displacement/time
displacement is the distance between final position & initial position;
time is the total time taken to cover this displacement.
for example: if a body starts from some initial point goes to a certain distance x and returns back to the initial position. So the total distance covered is 2x but displacement is 0 (zero) because initial & final position are same. So its speed is 2x/time while velocity is 0/t = 0(zero)

How do you find speed if you know the velocity?
Velocity is speed and direction
What is the Velocity of speed?
Velocity is the vector form of speed. It is the speed of an object in a specified direction.
Is speed equal to velocity?
Velocity is a vector, which means it has a direction, but speed isn't. Speed is the absolute value of velocity. Velocity can be negative, meaning that the speed is opposite to the direction that you're calling the positive direction.
Does average velocity and average speed have the same number?
velocity is a vector and speed is scalar. Velocity has magnitude and directions, with magnitude being speed. The magnitude of average velocity and average speed is the same.
Why is velocity and speed same unit?
Velocity is speed, plus an indication of direction. To indicate a velocity, you can indicate a speed (this will logically use units of speed), and a direction.
