If you have two of these, velocity(V) , Distance (S) and Time (T) You can find the third one with this formula V = S/T

• For 1) if you know the two distances you can use the formula (a + b)xy/ay + bx, where a is the first distance and x is the corresponding speed and b is the second distance and y is the corresponding speed, to find the average velocity (remember it only holds straight line motion) Suppose you are not given a and b but you are given a + b and a/b you can find the individual values. For 2) if you are meaning the round trip then the displacement is 0, therefore average velocity is 0.

• The only difference between speed and velocity is that velocity has a direction associated with it. speed=distance/time
