Answer:

see explanation below

Explanation:

Speed is the distance travelled per unit time irrespective of direction, so only magnitude is of importance, and that it is a scalar quantity. Speed can be calculated using the formula: #(distance)/(time)#

Velocity is the distance travelled per unit time in a specific direction, so both magnitude and direction are important, and that it is a vector quantity. Velocity can be calculated using the formula: #(displacement)/(time)#

Acceleration is the rate of change of velocity of an object. Magnitude and direction are both considered, so it is a vector quantity. Acceleration can be calculated using the formula: #a=(v-u)/t#, where #a#=acceleration, #v#=final velocity, #u#=initial velocity and #t#=time.
