Answer:
The "average speed" of the rider is 40 km/h.
Explanation:
The average speed of a rider finishes by bicycle is the total distance traveled by bicycle divided by the time to cover that distance.
[tex]\text { Average speed }=\frac{\text { total distance }}{\text { total time }}[/tex]
[tex]\Delta \mathrm{s}=\frac{\Delta \mathrm{d}}{\Delta \mathrm{t}}[/tex]
∆s =Average speed
∆d = total distance
∆t = total time
Total distance of the rider finishes by bicycle = 120 km
Total time of the rider's bicycle = 3 hours
[tex]\text { Average speed }=\frac{120}{3}[/tex]
Average speed = 40 km/h
The "average speed" of the rider is 40 km/h
