A cross -country skier moves from location A to location B to location C to location D . Each leg of the back -and-forth motion takes 1 minute to complete ; the total time is 3 minutes . (The unit is meters .) West East t 0min t=2min t=3min t=1min 20 60 100 120 100 160
Calculate the average speed and average velocity (in mi/hr) during the three minutes of recreation.
Location A => t=0 => 0
Location C => t=2 => 40
Location D => t=3 => 120
Location B => t=1 => 160
Total time 3min
