## Algebra 1: Common Core (15th Edition)

Let x = the traveler's speed off the walkway and let y = the speed of the moving walkway. We have the system: $x-y=2$ $x+y=6$ Use elimination to solve for x. $2x=8$ $x=4$ $\rightarrow y=2$ The traveler's speed off the walkway is 4ft/s, and the speed of the moving walkway is 2ft/s.
