A boat that travels at a speed of \(6.75 \mathrm{~m} / \mathrm{s}\) in still water is to go directly across a river and back ( \(abla\) Figure 3.34). The current flows at \(0.50 \mathrm{~m} / \mathrm{s}\).

(a) At what angle(s) must the boat be steered?

(b) 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.)
