 Question 607297: Two radio transmitters are positioned along the coast, 500 miles apart. A signal is sent simultaneously from each transmitter. The signal from trasmitter T1 is received by a ship's LORAN 700 microseconds after the ship receives the signal from T2. The radio signals travel at 0.186 mile per microsecond. Find an equation of the hyperbola, with foci at T1 and T2, on which the ship is located. Round parameters to the nearest tenth. Click here to see answer by richwmiller(9143)
