A boat can travel at a speed of 3.4 m/s in still water. A river that is 160 m wide has a current that flows 1.3 m/s due West.(adsbygoogle = window.adsbygoogle || []).push({});

a) If the boat points its bow directly across the river, how fast does the boat travel relative to the shore?

3.64 m/s

b) How long will it take to cross the river?

47.0588 s

c) Fow far downriver will it land (the distance on the bank from the point directly across from the starting point to the landing point)?

m

d) At what angle should the boat be pointed in order to arrive at a point directly across from the starting point? Assume North is directly across the river.

° E of N

e) How long does that take?

s

I got A and B but I don't know how to setup C -- Any ideas?
