What was his average speed and average velocity

Reference no: EM13672830

A man walks 3 miles east in 1 hour at a constant velocity, then walks two miles east at a constant velocity in 20 minutes, then two miles east at a constant velocity in 40 minutes, then rests for one hour and then turns around and walks eight miles west in two hours.

1. What distance did he walk?

2. What was his displacement?

3. What was his average speed?

4. What was his average velocity?
