Chart movement using latitude and longitude

To chart the movement of a polar bear, scientists attached a radio transmitter to its neck. Two tracking stations monitor the radio signals. Station B is 10 miles directly east of station A. On Monday, station A measured the direction of the bear at N43degreesE, and, station B, at N30degreesW. Three days later, the directions to the bear from the 2 tracking stations were, N24degreesE, and, N30degreesW, respectively. How much further from station B, was the bear after those 3 days?
