Bicycle travel first How distance between two place with the speed of 5 kilometre per hour and rest of her sister is the speed of 20 km per hour. The average speed of bicycle is:

Let the total distance covered be" s "km

Total time taken,

=(s/2)/5+(s/2)/20

=5s/40

Average speed,

=s/(5s/40)

=s*(40/5s)

=8 km/hr
