Problem

ProblemBeginning from a signpost, you run 60m to the right, then 60m back. The entire trip takes 24 seconds. What is your speed and velocity for the whole trip?

A

Speed = 5 m/s, velocity = 5 m/s

B

Speed = 2.5 m/s, velocity = 0 m/s

C

Speed = 5 m/s, velocity = 0 m/s

D

Speed = 0 m/s, velocity = 0 m/s
