Answer 1

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.

$\text { Average speed }=\frac{\text { total distance }}{\text { total time }}$

$\Delta \mathrm{s}=\frac{\Delta \mathrm{d}}{\Delta \mathrm{t}}$

∆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

$\text { Average speed }=\frac{120}{3}$

Average speed = 40 km/h

The "average speed" of the rider is 40 km/h .
