At some airports there are speed ramps to help passengers get from one place to another. A speed ramp is a moving conveyor belt that you can either stand or walk on. Suppose a speed ramp has a length of 105 m and is moving at a speed of 2.0 m/s relative to the ground. In addition, suppose you can cover this distance in 75 s when walking on the ground. If you walk at the same rate with respect to the speed ramp that you walk with respect to the ground, how long does it take for you to travel the 105 m using the speed ramp?
