There is no fixed speed, it depends on the energy in the weather system of which the cold front is a part. However cold fronts move faster than warm fronts, this leads to occluded fronts.
When a fast moving cold air mass collides into a warm air mass.
A slow moving front is relatively like a stationary front, bringing rain for quite a while as the front approaches, then when the front passes, it will bring cold weather for a longer period of time because the front will be around for a longer period of time. A fast moving front will bring cold for a shorter period of time and less rain as the front approaches. These are the simple effects of what will happen.
Cumulonimbus cloud
a WARM front occurs when a fast moving warm air mass overtakes a slower moving cold air mass.
Weather is associated with both kinds of fronts, just different kinds of weather. A warm front will typically have increasing temperatures, partly to mostly cloudy skies with low cloud base heights and sometimes a gentle, uniform rainfall. A cold front will typically have decreasing temperatures, partly to mostly cloudy skies with moderate to high cloud base heights, and sometimes heavy, showery rain.

Cold fronts tend to travel a little faster. When they catch up to the warm front, an occluded front is formed.
