Question

A bicycle traveled 150 meters west from point A to point B. Then it took the same route and came back to point A. It took a total of 2 minutes for the bicycle to return to point A. What is the average speed and average velocity of the bicycle? A. The average speed is 2.5 meters/second, and the average velocity is 2.5 meters/second east. B. The average speed is 0 meters/second, and the average velocity is 2.5 meters/second east. C. The average speed and average velocity are both 0 meters/second. D. The average speed is 2.5 meters/second, and the average velocity is 0 meters/second.

Answer 1

The average speed is 2.5 meters/second, and the average velocity is

0 meters/second.

Explanation: plato/edmentum

Answer 2

D. The average speed is 2.5 meters/second, and the average velocity is 0 meters/second.

The difference between speed and velocity is that, speed is a scalar quantity while velocity is a vector quantity.

Average speed = total distance/Total time

= (150 + 150) / (2×60)

= 300/120

= 2.5 m/s

Average velocity = Total displacement/ Total time

= (150 + -150) / (2 × 60)

= 0/120

= 0 m/s
