I'm having trouble solving part of this problem. Can anyone help? In climbing a wall, a caterpillar undergoes a complicated motion in which it ascends 3m and slips down 2m every 5min. What is its average speed and average velocity after 5min? I figured the avg. speed to be 0.02 m/s, but I'm having trouble with the avg. velocity. It's not making sense to me. The displacement is needed to find the solution, but I'm having a hard time determining the intial and final positions.
