A moving sidewalk in an airport moves people between gates. It takes Jason's 9-year-old daughter Josie 33 sec to travel 165 ft walking with the sidewalk. It takes her 7 sec to walk 21 ft against the moving sidewalk (in the opposite direction). Find the speed of the sidewalk and find Josie's speed walking on non-moving ground. The sidewalk moves at ft/sec.
