    If the question gives me a synoptic charts with an image of a frontal system in the ocean South West of Cape Town and it asks based on the synoptic situation in the image the temperate cyclone will reach Cape Town within
    A. 1 day
    B. 2 days
    C. 3 days

    You would have to look at the image and then based on the scale of the chart you would roughly work it out how far it would move, by working out the distance from the front to in this case Cape Town.

    Then using the speed, distance and Time formula you can work out how long it would take.

    • Cold fronts generally advance at average speeds of 20 to 25 mph.
    • Warm fronts usually move about half as fast, at about 10 to 15 mph, and sometimes even slower.
