A rider finishes a 120 km bicycle trip in 3 hours. The average speed of the rider is_____.

A.)4 km/h
B.)3.6 km/h
C.)360 km/h
D.)40 km/h

Answer 1

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

Step-by-step 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 }=(120)/(3)`

Average speed = 40 km/h

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