The short answer is that velocity is the speed with a direction, while speed does not have a direction.
Speed is a scalar quantity -- it is the magnitude of the velocity. Speed is measured in units of distance divided by time, e.g. miles per hour, feet per second, meters per second, etc....
Velocity is a vector quantity -- when giving the velocity we must specify the magnitude (the speed) and the direction of travel. For example you might drive 100km/hr (the speed) in a northerly direction.
This is analogous to the difference between distance (a scalar quantity) and displacement (the distance with direction.)
