speed is the ratio of distance to the time taken..
speed = distance / time
m/s...
velocity is the ratio of displacement to the time taken...
velocity = displacement / time
m/s...
the acceleration is the ratio of velocity to time taken....
acceleration = velocity / time.
m/s2

Answer :
1. MEASURE OF RATE OF MOTION : SPEED --
While discussing motion, we learn that different objects may take different times to cover a given distance.Some objects may move fast but some other objects may move slowly.To identify slow or fast motion, we define a term known as Speed.
Speed of a moving object is the distance travelled by it in unit time.
Let an object cover a distance s in time t, then the speed of an object during this time interval is given as :
2. SPEED WITH DIRECTION : VELOCITY
Speed of an object gives its magnitude of rate of motion but it does not tell us anything about the direction of motion. If we specify the direction of motion too, then concept of motion becomes more comprehensive.For this purpose, we define a new term Velocity.
Velocity of an object is its speed moving in a particular direction. Thus, velocity of an object may be defined as the displacement of the object per unit time.
3. RATE OF CHANGE OF VELOCITY : ACCELERATION.
During uniform motion along a straight line, the velocity of an object remain constant and it does not change with time. However, in nonuniform motion, the velocity of the object varies. The velocity may have different values at different instants of time as well as different points of the path and hence, change in velocity of the object during a given time interval is not zero. For such a situation, we define yet another term Acceleration.
The acceleration of an object is measure of the change in velocity of an object per unit time.
Alternately, the acceleration of an object is defined as the rate of change of velocity of the object with time.
