1. The problem statement, all variables and given/known data When the moving sidewalk at the airport is broken, as it often seems to be, it takes you 54 s to walk from your gate to baggage claim. When it is working and you stand on the moving sidewalk the entire way, without walking, it takes 72 s to travel the same distance. How long will it take you to travel from the gate to baggage claim if you walk while riding on the moving sidewalk? 2. Relevant equations v=v'+V (they are vectors) 3. The attempt at a solution I try to set up the equation but i cant seem to figure out what v and v' are so i try to add and subtract the obvious numbers but i cant seem to get the right answer.
