The time it takes for a pulse to travel the length of the wire depends on the speed of the pulse and the length of the wire. However, without specific information about the tension in the wire or the linear mass density, we cannot directly calculate the speed of the pulse. The given options suggest an estimation or an assumed context where the speed of sound or a similar mechanism for pulse travel might be considered. Assuming a typical speed for such a pulse in a medium like a wire, 1.0 s is a reasonable estimate for the pulse to travel 2.45 m, considering that sound travels at approximately 343 m/s in air at room temperature, and would likely travel slower in a wire. This is a rough estimation and the actual time could vary based on the properties of the wire and the pulse.
