1. The problem statement, all variables and given/known data I'm not sure if my graph for this problem is correct... I've attached it below, can someone please help me? The problem is: In heavy rush-hour traffic you drive in a straight line at 12 m/s for 1.5 minutes, then you have to stop for 3.5 minutes, and finally you drive at 15 m/s for another 2.5 minutes. a) Plot the position-versus-time graph for this motion. your plot should extend from t=0 to t=7.5 minutes. b) Use your plot from part a to calculate the average velocity between t=0 and t=7.5 minutes. 3. The attempt at a solution Also, I'm not quite sure how to get average velocity out of this. I know that it's supposed to be distance divided by time, so I figured I could get the distance by multiplying 12 m/s by 90 seconds plus 15 m/s for 150 seconds to get 3330 meters, and then divide that by the total amount of time, 450 seconds, so my answer is 7.4 m/s but I don't know if that is right.
