A change in speed over a given period of time is
velocity
motion
speed
acceleration
Calculate the speed of a sprinter who ran 200 meters in 20 seconds.
10m/s
10 km/s
10 m/hr

The measure of how quickly something moves or the distance it moves in a given amount of time is called
acceleration
velocity
speed
distance
What is the formula to calculate speed?
Speed = time + distance
Speed = distance/time
Speed = distance x time
Speed=displacement/time
