1. The problem statement, all variables and given/known data ( URL of image in case it doesn't display : http://imgur.com/wrzYH.png ) The axes x and y are measured in miles. In the figure, the LORAN stations at A and B are 520 mi apart, and the ship at P receives station A's signal 2,640 microseconds (ms) before it receives the signal from B. A) Assuming that radio signals travel at 960 ft/ms, find | d(P, A) - d(P, B)| B) Find an equation for the branch of the hyperbola indicated in red in the figure, using miles as the unit of distance. C) If A is due north of B, and if P is due east of A, how far is P from A? My attempt at a solution The only thing I was able to somewhat figure out was Part A, but i'm not sure if my logic was correct. I multiplied 960 by 2640 to get 2,534,400 and put that was my answer.
