Answer:
0.417 m/s
Step-by-step explanation:
Speed is the change of rate in position (distance traveled) by time, it represents how fast or slow something or someone is moving. It is a scalar measure since it does not take into account direction, if direction was taken into account the resulting vectorial measure would be called velocity.
So in order to calculate the speed we would divide the distance moved by the time taken to move:
1500m/3600s = 0.416666 m/s
note that the units come given by the units of the numerator and denominator meters per second.
