You can put this solution on YOUR website! A plane leaves an airport and flies at 360mi/hr on a course of 103° 15' for 1hr and 33minutes. Then it changes course to 236°45' and flies for 48minutes. How far is it from the airport? If it wished to return, what would be its course?
--------------------
360 mi/hr = 6 mi/minute
103° 15' = 103.25°
236° 45' = 236.75°
----
Label the start point A, then B & C
AB = 6*93 = 558 miles (side c)
BC = 6*48 = 288 miles (side a)
Angle at B = 46.5 degs
-----
Side b = distance from start
