    Answer:

      v_average = 15 m / s

    Explanation:

    The average speed can be found in two ways,

    * taking the distance traveled and divide it by the time spent

    * taking the velocities in each time interval and then finding the weighted average by the time fraction

                  v_average = 1 / t_total ∑  v_{i} t_{i}vi ti

    Let’s apply this last equation

                   

    Total time is

                   t = t₁ + t₂

                   t = 10 + 10 = 20   min

                  v_average = 10/20 10 + 10/20 20

                  v_average = 10/2 + 20/2

                  v_average = 15 m / s
