** 12. Wilmington, North Carolina, is 5024 km due east of Santa Barbara, California. High- speed communication between the two cities can be accomplished by use of satellite commu- nication to a satellite that is a distance of 3456 km away from each city or by direct fiber optic 1.62. How long would cable between the two cities in a fiber whose index of refraction is n = it take each signal to go from Santa Barbara to Wilmington?
