P, Q and R are three towns. Q is 40 km N 72°E of P and R is 48 km S 55° E of P. Find the distance and bearing from Q to R. Round the distance to the nearest 0.1 km and the bearing to the nearest minute.

Answer 1

If P is at (0,0)
Q is at (38.04,12.36)
R is at (39.32,-27.53)
so,
R-Q = (1.28,-39.89)
the bearing,distance are 39.9km S1°50'W
