Hi

 300km/6hr = 50kmph 

Answer by John10(297)   (Show Source): You can put this solution on YOUR website!
 As the problem gave you the distance (d) and time (t), we use the relationship of distance, time, and speed (s):

                  

                            s = d/t = 300/6 = 50 km/h



I recommend that you check the units to make sure your answer is correct.
