    Velocity and Displacement
    A pronghorn antelope has been observed to run with a top speed of 97 km/h.
    Suppose an antelope runs 1.5 km with an average speed of 85 km/h, and then runs 0.80 km with an average speed of 67 km/h.

    a. How long will it take the antelope to run the entire 2.3 km?
    b. What is the antelope’s average speed during this time?

    Hint: distance = rate times time. Which can be rearranged to time = distance/rate. Take a shot at figuring the answer and post back with what you get - we'll be happy to check it for you.
