Question

A horse travels 80 meters south in 20 seconds. What is its average velocity?

A. 4 m/s
B. 0.25 m/s
C. 4 m/s south
D. 0.25 m/s south

Answer 1

Average velocity is a vector unit (i.e. includes magnitude and direction) calculated by working out distance ÷ time:

80 metres ÷ 20 seconds = 4 metres/seconds (m/s)

Therefore, your final answer is C. 4 m/s south.
