Answer:
This is the instantaneous speed of Greg(the bike rider)
Step-by-step explanation:
greg is in a bike race. at mile marker four (out of ten), his speed was measured at 13.5mph. which best describes the measured number
instantaneous speed is the speed of an object at a particular time
speed of an object is the distance moved per time. when an object has covered a particular distance in space. The instant time can be recorded and then we calculate the instantaneous speed. peed is measure in meters /seconds=m/s
It is known as a scalar quantity because it has magnitude but no direction.
