If a boat has a speed of 6.75 m/s and goes north directlyacross a river and back. The current is moving east at 0.50 m/s. Atwhat angles must the boat br steered? How long does it take for theround trip? tan-1 0.50 m/s 6.75 m/s = 85.76 degrees and to find thetime 150 m /6.75 = 22.2 s Then for the round trip 22.2 s * 2 = 4.44s.
