2. The problem with your problems is that you have to convert the bearings and courses into a more convenient format of angle measure:
Courses are given wrt to North N = 0°, measured clockwise. Thus
N = 0°
E = 90°
S = 180°
W = 270°
A course of S62°50'W = 180° + 62°50' = 242°50'
A course of S52°40'E = 180° - 52°40' = 179°60' - 52°40' = 127°20'
3. Draw a rough sketch for each problem.
4. The problem #2 can't be solved because the traveling time of the 2nd course is missing.
