As you hurry to catch your flight at the local airport, you encounter a moving walkway that is 61 m long and has a speed of 2.2 m/s relative to the ground. If it takes you 49 s to cover 61 m when walking on the ground, how much time will it take you to cover the same distance on the walkway? Assume that you walk with the same speed on the walkway as you do on the ground.
