= = The boat has a speed b/w 23 ft/sec in still water. It is supposed to cross a 360-ft wide river from point A to point B, which is located at a distance of AB 520 ft from A, on a straight line. If the 9 ft/sec, determine the speed vɩ of the boat, the direction angle which the boat should take to stay on line AB, and the time needed to make the crossing. (v = 15.6 ft/sec, 0 = 15.7°, t = 33.2 sec) river flows with a velocity vw = A d Vw B Vb/w 0
