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
mi due east of station A on a coastline.A ship received the signal from B
microseconds (
before it received the signal from A.Assuming that radio signals travel at a speed of
and if the ship is due north of B, how far off the coastline is the ship? Round yourAnswer to the nearest mile.Select the correct Answer
