Calcular la rapidez promedio una bicicleta recorrió 10 minutos a 10 m/s y otros 10 minutos, a 20 m/s.

  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 ∑  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

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.
