Question

pre - class quiz: average speed & average velocity
1 multiple choice 0.5 points
video (timestamp ~1:14): the video describes speed as how fast. which ratio defines average speed?
\tdisplacement / total distance traveled
\tdisplacement / total time
\ttotal distance traveled / total time
\ttotal distance traveled / displacement

Explanation:

Average speed is a scalar quantity that measures the overall rate of motion, calculated by dividing the total path length traveled by the total time taken to cover that path. Displacement is used for average velocity, not speed.

Answer:

total distance traveled / total time
