Question
(A) Two LORAN (long range navigation) stations A and B are situated along a straight shore, where A is 200 miles
west of B. These stations transmit radio signals at a speed 186 miles per millisecond. The captain of a ship
travelling on the open sea intends to enter a harbor that is located 40 miles east of station A.
Due to the its location, the harbor experiences a time difference in receiving the signals from both stations. The
captain navigates the ship into the harbor by following a path where the ship experiences the same time
difference as the harbor.
(a) What time difference between station signals should the captain be looking for in order the ship to
make a successful entry into the harbor?
(b) If the desired time difference is achieved, determine the location of the ship if it is 75 miles offshore.
