    step-by-step explanation:

    x^2 -12x + 36 + y^2 = 36

    x^2 + y^2 = 12x

    r^2 = 12rcos(theta)

    r = 12 cos(theta)

    Answer:

    The semi-trailer truck has the fastest average speed

    Step-by-step explanation:

    Let’s recall that the formula of the average speed is:

    Average speed = Distance/Speed

    Now, we can calculate the average speed for each class of vehicle, as follows:

    Flatbed truck average speed = 144/5 = 28.8 miles per hour

    Semi-trailer truck average speed = 327/4 = 81.75 miles per hour

    Tanker truck average speed = 589/15 = 39.27 miles per hour

    Which truck has the fastest average speed?

    The semi-trailer truck has the fastest average speed
