a.)4 km/h
b.)3.6 km/h
c.)360 km/h
d.)40 km/h

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.

∆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

Average speed = 40 km/h

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

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
