How will the travel time of the second pulse compare to that of the first?

Question

A long spring (a Slinky) is stretched out on the floor, and the time it takes a wave pulse to travel from one end to the other is measured. Then, a small, separate piece of tape is wrapped around each coil of the Slinky and a second pulse is sent from one end to the other. How will the travel time of the second pulse compare to that of the first?
