    Why don't you start by writing equations relating the speed of the invidiual planes and their repective distance and time taken in relation to each other?

    I don't how ... if I can write the equation I can probably solve it. Its suppose to be a duaradratic but I don't get how ???

    Start with distance = rate * time.

    Cessna and Beechcraft need two row; a row for each.
    Rate, Time, Distance each need a column. Fill in expressions according to your description. Your unknown speed seems to be that of the Cessna, so that is your variable. For simplification purposes, "speed" is the same as "Rate" for this problem description (which is not always correct).
