Three LORAN radio transmitters, A, B, and C, are located 200 miles apart along a straight coastline.
Question:
a. Find d2 - d1. Express your answer in miles (1 mi = 5280 ft).
b. Find d3 - d1. Express your answer in miles.
c. Use the fact that d2 - d1 is constant to write the equation of the hyperbola represented in 10a. Note that transmitters B and C are located at the foci.
d. Write the equation of the hyperbola represented in 10b.
e. Graph the hyperbolas and find the coordinates of the location of the ship. How can you be sure which of the intersection points represents the ship?
