A radio station called WWV broadcasts from Fort Collins, Colorado. This station broadcasts the time and has served as a “standard clock” for many years. The radio waves transmitted by this station travel through the atmosphere at approximately the speed of light, so they reach different listeners at different times. Suppose the signal announcing 9:00 AM reaches a person in Chicago at time t = 0 (on her local stopwatch). At what time (on this stopwatch) will this signal reach
(a) a listener in New York City?
(b) A listener in Honolulu?
