A boat that travels at a speed of 6.75 m/s in still water is to go directly across a river and back, as shown in the figure below. The current flows at 0.50m/s
At what angles must the boat be steered?
How long does it take to make the round-trip? (Assume that the boat's speed is constant at all times, and neglect turnaround time.
