A runner travels 450 meters north, 850 m east, 800 m north, 1200 m west, 400 m south and 600 m east in 30 minutes. What is the average speed for the run? What is his average velocity?

Answer #1

Average speed =Total Distance/ Time

Average Speed = (450+850+800+1200+400+600) /(30 *60)

Average Speed =4300 /1800

Average Speed =2.389 m/s

Average velocity = Total displacement /Time

T

Average Velocity = Total Displacemet /Time

Average Velocity = Shortest distance (GA ) /Time
