The pilot of a plane flying due north is notified by the flight controller that there is a second plane flying south at about the same altitude and located in the same general area. The pilot is told that the southward bound plane is currently located at a position which is 12.4 km, 102.4° from her own plane.

How many kilometers to the north is the second plane?

How many kilometers to the west is the second plane?

If the two planes both have an airspeed of 254 km/hr, then how much time (in minutes) will elapse before the planes are side by side?
