Question

You get out of school and walk north for 20 minutes. You

travel 1. 6 km. What is your average velocity?

1

Answer 1

4.8 km/hour because you times everything by 3

Answer 2

Explanation:

Velocity is change in displacement over change in time.

v = d/t

In this problem, d = 1.6 km and t = 20 minutes

To find the velocity, divide 1.6 by 20, and you get 0.08 km/min.

You could also convert this to km/hour by dividing 1.6 km by 1/3 hours, and the velocity would be 4.8 km/hour.
