question 69

Multiple Choice

In the LORAN (LOng RAnge Navigation) radio navigation system, two radio stations located at A and B transmit simultaneous signals to a ship or an aircraft located at P. The onboard computer converts the time difference in receiving these signals into a distance difference , and this, according to the definition of a hyperbola, locates the ship or aircraft on one branch of a hyperbola (see the figure) . Suppose that station B is located L = mi due east of station A on a coastline. A ship received the signal from B microseconds (µs) before it received the signal from A. Assuming that radio signals travel at a speed of ft /µs and if the ship is due north of B, how far off the coastline is the ship? Round your answer to the nearest mile.

• A) miles
• B) miles
• C) miles
• D) miles
• E) miles
