[QUOTE="nviander, post: 4900724, member: 529358"] [h2]Homework Statement [/h2] In going to the store, you walk half of the distance at 1 m/s. At this point, you decide that you should pick up the pace. You would like to average 2 m/s for the entire trip. How fast must you move for the remainder of your trip in order to do so? Hint: the answer is not 3 m/s! [h2]Homework Equations[/h2] v = 0.5 (v[1] + v[2]) [h2]The Attempt at a Solution[/h2] v = 0.5 (v[1] + v[2]) 2 = 0.5 (1 + v[2]) 2 = 0.5 + 0.5v[2]) 1.5 = 0.5v[2] 3 = v[2] [/QUOTE]
