Velocity is different from speed.
Speed is average rate of change in distance per unit time.
Velocity is rate of change in distance per unit time in particular direction.
For example,
car travel in speed of 2 m/s
(average rate change of 2 meters per seconds)
car travel in velocity of 2 m/s
(rate change of 2 meters per second in forward direction)
car travel in velocity of -2m/s
(rate change of 2 meters per second in backward direction)

velocity is the distance traveling per unit time. An example is 5 miles per hour. Velocity is this ratio in a straight continuous line. If a car is traveling straight it has a constant velocity. As soon as it starts going around a bend its velocity changes because it is now going in a constantly changing direction instead of one continuous one.

Basically Velocity is the speed something is travelling at with a direction added:
Examples:
1. Car travelling at 60 km/h
2. Car travelling at 60 km/h north
(Take note velocity is a vector, because of the direction given with the speed)

is the ithe ratio of distance to time... generally meters to seconds
