Which of the following does not indicate velocity?
a.
14 m/s sse
b.
40 km/h toward the town square along the main street
c.
80 km/h going from new york toward new jersey
d.
28 km from los angeles to catalina island

The correct answer is D. 28 km from Los Angeles to Catalina Island

Explanation:

In physics, velocity is a concept is classical mechanics that includes both the direction of motion and the speed, which is defined by the distance traveled and the time it takes to travel the distance. In the case of "28 km from Los Angeles to Catalina Island" this does not indicate velocity as the distance traveled "28 km" is included but not the time or duration interval, which means we do not know the speed in this case and therefore, this does not indicate velocity. Thus, the correct answer is D.
