    Remember that:

    Average speed = (Total Distance)/(Total Time)

    And that:

    Speed = Distance / Time

    1. Find the time to cover distance p.
    2. Find the time to cover distance q.
    3. Find the total distance.
    4. Find the total time.
    5. Divide total distance by total time.
