As you hurry to catch your flight at the local airport, you encounter a moving walkway that is 90 meter long and has a speed of 2 meter per second relative to the ground.
Part A. If it takes you 68 second to cover 90 meter when walking on the ground, find how long will it take you to cover the same distance on the walkway? Suppose that you walk with the same speed on the walkway as you do on the ground.
