A boat sails for 3 hours at 25 mph in a direction 150 degrees and 14 minutes. How far south has it sailed?

Solution

150.14° - 180° = 29.86°
Sin 29.86° = Far South / Distance Traveled
Far South = Sin 29.86° (Distance Traveled)
Far South = 0.4979 (25 m/hr x 3 hr)

=============================
Far South = 37.3425 miles Ans
