Average Speed and Motion

What is the difference between instantaneous speed and average speed?

• Average speed happens in a particular instant, Instantaneous speed is the speed of an object over a longer period of time.

• Instantaneous speed is never right, average speed is always right

• Instantaneous speed happens in a particular instant, Average speed is the speed of an object over a longer period of time.

• Do not pick this answer

How would you find the average speed of a marathon runner throughout an entire race?

• Ask a magic 8 ball

• You would take the entire distance the runner traveled and divide the distance by the total time it took the runner to complete the race.

• run along side them and eyeball it

• Ask Alexa

Calculate the speed:
A Motorcycle traveled 368 Km in 8 Hours

• 2944 Km/hr

• 4.5 Km/hr
