Answer is 20.0 km per hour.


Explanation;


S = d/t


Where, S is the speed, d is the distance and t is the time taken.


Here,

    d = 50.0 km

     t = 2.5 hours


By applying the formula,

  S = 50.0 km / 2.5 hours

      = 20.0 km per hour


Hence, the average speed of the cyclist is 20.0 km per hour.
