A traveler is walking on a moving walkway in an airport The Traveler must walk back on the walkway to get a bag he forgot the Travelers ground speed is 2ft/s against the walkway and 6ft/s with the walkway what is the Travellers speed off the walkway what is the speed of the moving walkway
let the speed off the walk way be x and speed of the walkway be y x+y=6....i x-y=2....ii adding the above equation we get: 2x=8 thus x=4 ft/s and y=6-4=2 ft/s thus the speed off the walk way is 4 ft/s the speed of the moving walkway is 2 ft/s
